Special Issue Information

Dear Colleagues,

In the era of digital transformation, which includes converting any processes into a quantified format suitable for future analysis, there is an increasing demand on simulations and experiments on heat and fluid flow for a variety of single and multiphase flows and boundary conditions. The importance of heat and fluid flow is still growing in all aspects of our lives, starting from nature, and ending with industrial processes. Thanks to computational fluid dynamics and its commercial packages, we can design and perform the optimization of various processes. Continuously increasing ability and understanding of heat and mass transfer phenomena has contributed significantly to effectively managing a variety of processes.

This Special Issue on “Numerical Heat Transfer and Fluid Flow 2024” in the scientific journal Energies is addressed to specialists from all over the world who deal with mathematical modeling and experiments on heat and fluid flow. We welcome papers dealing with solutions of problems of scientific and industrial relevance in the broad fields of heat transfer and fluid transportation, including natural resources, biomedical, industrial processes, etc. Papers addressed to the Special Issue will not only solve specific engineering problems but will serve as a catalyst on future directions and priorities in numerical heat transfer and fluid flow.

Topics of interest for publication include, but are not limited to, the following:

  • Numerical simulations of mass and/or heat transfer.
  • Computational fluid dynamics.
  • Experiments and simulations of single or multiphase flows, including Newtonian and non-Newtonian fluids.
  • Modeling, optimization, and control of heat transfer and fluid flow.
  • Mini and microflows.
  • Turbulence.
  • Modelling of turbulence.
  • Flowing phase interactions.
  • Energy saving processes, including an increase or decrease in frictional losses and/or heat transfer.

The Fokker–Planck (FP) equation represents the drift and diffusive processes in kinetic models. It can also be regarded as a model for the collision integral of the Boltzmann-type equation to represent thermo-hydrodynamic processes in fluids. The lattice Boltzmann method (LBM) is a drastically simplified discretization of the Boltzmann equation for simulating complex fluid motions and beyond. We construct new two FP-based LBMs, one for recovering the Navier–Stokes equations for fluid dynamics and the other for simulating the energy equation, where, in each case, the effect of collisions is represented as relaxations of different central moments to their respective attractors. Such attractors are obtained by matching the changes in various discrete central moments due to collision with the continuous central moments prescribed by the FP model. As such, the resulting central moment attractors depend on the lower-order moments and the diffusion tensor parameters, and significantly differ from those based on the Maxwell distribution. The diffusion tensor parameters for evolving higher moments in simulating fluid motions at relatively low viscosities are chosen based on a renormalization principle. Moreover, since the number of collision invariants of the FP-based LBMs for fluid motions and energy transport are different, the forms of the respective attractors are quite distinct. The use of such central moment formulations in modeling the collision step offers significant improvements in numerical stability, especially for simulations of thermal convective flows under a wide range of variations in the transport coefficients of the fluid. We develop new FP central moment LBMs for thermo-hydrodynamics in both two and three dimensions, and demonstrate the ability of our approach to simulate various cases involving thermal convective buoyancy-driven flows especially at high Rayleigh numbers with good quantitative accuracy. Moreover, we show significant improvements in the numerical stability of our FP central moment LBMs when compared to other existing central moment LBMs using the Maxwell distribution in achieving high Peclet numbers for mixed convection flows involving shear effects.

Numerical investigations of heat transfer for forced, mixed, and natural convection conditions within an annular channel are carried out. The main objective was to investigate, for the first time, the effect of the radial cylinder array on heat transfer in the annular channel with the rotating cylinder. The governing equations for velocity and temperature with the Boussinesq approximation were solved using the finite-volume method. The heat transfer quantities were obtained for different Rayleigh numbers (104–106), the radius ratios (1.4–2.6), the radial cylinder spacing, and for different rotating velocities in the form of the Richardson number (10−2–104). The Prandtl number was 0.7. It has been shown that radial cylinders do not influence significantly the intensity and the local distribution of heat transfer on the inner rotating cylinder. The Nusselt number was 1.4–2.0 times higher on the radial cylinder array for all convection modes relative to the outer flat surface. For all annuli gaps with radial cylinders, the maximal values of the Nusselt number were observed with an increase of the radial spacing of cylinders. Full article
