Abstract

:
The present communication examines the magnetohydrodynamic (MHD) squeezing flow of Jeffrey nanofluid between two parallel disks. Constitutive relations of Jeffrey fluid are employed in the problem development. Heat and mass transfer aspects are examined in the presence of thermophoresis and Brownian motion. Jeffrey fluid subject to time dependent applied magnetic field is conducted. Suitable variables lead to a strong nonlinear system. The resulting systems are computed via homotopic approach. The behaviors of several pertinent parameters are analyzed through graphs and numerical data. Skin friction coefficient and heat and mass transfer rates are numerically examined.

1. Introduction

The homogenous mixture of ultrafine nanometer-sized particles and convectional heat transfer base liquids is termed as nanofluid. Nanomaterials have a key role in the industrial and engineering processes like processing of coolants for the nuclear reactors, transformer coolant and radiation therapy in cancer treatment etc. Furthermore, the magneto-nanofluid is very helpful in various sectors including sterilizing devices, oil recovery from the underground reservoirs, gastric medications, and tumor elimination with hyperthermia. The small sized nanoparticles (which are mostly metallic, nonmetallic, metal-oxides) are good thermal conductors. For this reason, the nanofluid in comparison to the base fluid has greater thermal efficiency. Choi [1] proposed the idea of nanofluid. He argued that the addition of nanoparticles into the base fluid enhances the thermal performance of base fluid. Buongiorno [2] provided expressions including thermophoresis and Brownian motion. Later on, numerous researchers discussed the flows of nanofluid under different geometries. The relevant literature can be seen through the investigations [3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20] and several studies therein.
Squeezing flow between the parallel disks has received the attention of recent researchers due to widespread applications of such flows in various mechanical engineering disciplines. The flow is generated because of two parallel approaching surfaces in relative motion. The parallel approaching surfaces phenomena along with the relative motion is mostly used by the engineers in the modeling of flow of oil in bearings, determination of capacity of load-bearings, compression and injection modeling, etc. (see [21,22]). Stefan [23] reported the squeezing flow for lubrication approximation. Domairry and Aziz [24] studied magnetohydrodynamic squeezing flow of viscous liquid bounded by parallel disks. Siddiqui et al. [25] examined squeezing flow subject to an applied magnetic field. Rashidi et al. [26] performed an analysis of hydrodynamic squeezing flow by developing series solutions. Some other investigations on squeezing flow can be seen in the studies [27,28,29,30].
The prime interest in the present communication is to venture further into the regime of the squeezing flow of non-Newtonian nanofluid. Therefore, the explicit contribution here is as follows: firstly, to formulate the relevant problem for constitutive relations of the Jeffrey fluid model; secondly, to analyze Brownian motion and thermophoresis; thirdly, to consider magnetohydrodynamics of nanofluid; and fourthly, to entertain the idea of permeable characteristics of lower disks. The upper impermeable disk moves towards the lower disk with time-dependent velocity. Problem formulation is made through small magnetic Reynolds number approximation. The homotopy analysis technique (HAM) [31,32,33,34,35,36,37,38,39,40] is applied to obtain the convergent solutions of the governing equations. The present study has been arranged as follows. The next section presents problem development. Section 3 depicts the development convergent series solutions. Analysis for convergence and discussion have been examined in Section 4 and Section 5, respectively. Section 6 gives the main outcomes of the present study. Note that the considered Jeffrey fluid, although capturing the salient features of relaxation and retardation time, is not able to predict the shear thinning/shear thickening and normal stress effects.

2. Formulation

Consider magnetohydrodynamic squeezing flow of a Jeffrey nanofluid between the two parallel disks. The distance between the parallel disks is h ( t ) = H ( 1 - α t ) 1 / 2 . The upper disk is at z = h ( t ) , whereas the lower permeable disk is at z = 0 . A magnetic field B ( t ) = B 0 ( 1 - α t ) - 1 / 2 is taken transverse to the flow. Here, the induced magnetic field is neglected for a small magnetic Reynolds number [41,42,43]. Brownian motion and thermophoresis phenomena are accounted. The governing equations for Jeffrey nanofluid are differences in traffic flow

3.2. mth-Order Deformation Equations

L f f m η - χ m f m - 1 η = f R m f η ,
L θ θ m η - χ m θ m - 1 η = θ R m θ η ,
L ϕ ϕ m η - χ m ϕ m - 1 η = ϕ R m ϕ η ,
f m 0 = f m 0 = 0 ,   θ m 0 = ϕ m ( 0 ) = 0 ,
f m 1 = f m 1 = 0 ,   ϕ m 1 = θ m 1 = 0 ,
R m f η = f m - 1 v - S q 1 + λ 1 η f m - 1 + 3 f m - 1 - 2 k = 0 m - 1 f m - 1 - k f k + β 2 η f m - 1 v + 5 f m - 1 i v + k = 0 m - 1 f m - 1 - k f k - 3 k = 0 m - 1 f m - 1 - k f k i v - M 2 1 + λ 1 f m - 1 ,

R m ϕ η = ϕ m - 1 + N t N b θ m - 1 + P r L e S q k = 0 m - 1 f m - 1 - k ϕ k - η ϕ m - 1 ,
χ m = 0 ,   m 1 , 1 ,   m > 1 .
The general solutions ( f m , θ m , ϕ m ) consisting of the special solutions ( f m , θ m , ϕ m ) are
f m η = f m η + B 1 + B 2 η + B 3 η 2 + B 4 η 3 ,
θ m η = θ m η + B 5 + B 6 η ,
ϕ m η = ϕ m η + B 7 + B 8 η ,
where the constants B i ( i = 1 - 8 ) are computed through the boundary conditions ( 41 ) and ( 42 ) with values
B 1 = f m η η = 0 ,   B 2 = f m η η η = 0 , B 3 = - 3 f m η η = 1 + f m η η η = 1 - 3 B 1 - 2 B 2 , B 4 = 2 f m η η = 1 - f m η η η = 1 + 2 B 1 + B 2 , B 5 = - θ m η η = 0 ,   B 6 = θ m η η = 0 - θ m η η = 1 , B 7 = - ϕ m η η = 0 ,   B 8 = ϕ m η η = 0 - ϕ m η η = 1 .

4. Convergence Analysis

Clearly, the approximate series solutions involve the nonzero auxiliary parameters f , θ and ϕ . To get the appropriate values of f , θ and ϕ , the - curves are plotted at 20th order of deformations. Figure 1 and Figure 2 clearly show that the convergence zone exists inside the ranges - 1.30 f - 0.15 , - 1.45 θ - 0.25 and - 1.40 ϕ - 0.20 for lower disk case η = 0 and - 1.10 f - 0.15 , - 1.35 θ - 0.25 and - 1.35 ϕ - 0.10 for upper disk case η = 1 . Table 1 depicts that 16th order of deformations is sufficient for convergent homotopic solutions for lower disk, whereas the 18th order of deformations is necessary for convergent homotopic solutions regarding upper disks (see Table 2).

5. Discussion

This portion explores the effects of various pertinent parameters including Deborah number β , Lewis number L e , Brownian motion parameter N b , Prandtl number P r , thermophoresis parameter N t and squeezing parameter S q on temperature θ η and concentration ϕ η profiles. Figure 3 shows the the impact of Deborah number β on the temperature field θ η . It is observed that the temperature field θ η decreases with the increase in the Deborah number β . Figure 4 illustrates the impact of Brownian motion parameter N b on temperature field θ η . Here, temperature field θ η is increased by enhancing Brownian motion parameter. Variation of thermophoresis parameter N t on temperature field θ η is sketched in Figure 5. Larger values of thermophoresis parameter N t show higher temperature fields. Physically larger N t causes an enhancement in temperature distribution. This is because of a stronger thermophoretic impact. Figure 6 shows temperature against P r . Lower temperature is noticed for larger P r . Figure 7 indicates that larger squeezing parameter S q guarantees a decay in temperature θ η . Figure 8 elucidates the impact of Deborah number β on the concentration profile ϕ η . The concentration field ϕ η is decreased by increasing the Deborah number β . Figure 9 shows the impact of Brownian motion parameter N b on concentration profile ϕ η . Concentration profile is reduced for larger values of Brownian motion parameter N b . Figure 10 shows behavior of thermophoresis parameter N t on concentration field ϕ η . Here, concentration field is enhanced for larger thermophoresis parameter. Figure 11 elucidates the concentration for variation of Lewis number L e . Obviously larger L e leads to a large concentration field. Figure 12 sketched the concentration field ϕ η against Prandtl number P r . Larger P r shows concentration field. Figure 13 declares that the increasing values of squeezing parameter S q lead to higher enhancement. Table 3 is developed to validate the present results with the previously published results in a limiting sense. From this Table, we analyzed that the present HAM solution have good agreement with the previous solution by Hashmi et al. [6] in a limiting sense. Table 4 consists of skin friction at the lower and upper disks. Here, the skin friction coefficient at the lower and upper disks are higher for increasing Deborah number and squeezing parameter. Table 5 is computed to examine the numerical data of local Nusselt number at the lower and upper disks for several embedding parameters. It is observed that local Nusselt number enhances at both lower and upper disks for larger Lewis number while the reverse is found for Prandtl number. Table 6 depicts numerical data of local Sherwood number at the lower and upper disks for various values of pertinent parameters. Here, we noticed that local Sherwood number increases at both lower and upper disks for increasing values of squeezing parameter.

6. Conclusions

Magnetohydrodynamic (MHD) squeezing flow of Jeffrey nanofluid between two parallel disks is examined. The key points of presented analysis are mentioned below:
  • Larger values of Deborah number correspond to lower temperature and concentration profiles.
  • Both temperature and concentration profiles are higher for larger values of thermophoresis parameter.
  • Effects of Brownian motion parameter on temperature and concentration profiles are quite the opposite from each other.
  • Larger values of Prandtl number show opposite trends for temperature and concentration profiles.
  • Effects of squeezing parameter on temperature and concentration profiles are quite opposite to each other.
  • The present analysis reduces to a Newtonian nanofluid flow situation when β = λ 1 = 0 .
