Special Issue Information

Dear Colleagues,

It is my immense pleasure to announce the launch of a Special Issue of Energies entitled “Computational Fluids Dynamics in Energy Conversion and Heat Transfer”. The tremendous development of computational resources in the past few decades has made CFD a powerful tool for analysing thermodynamic systems. The aim of this Special Issue is to provide a platform for high-quality original research articles on the theoretical foundations and applications of computational fluid dynamics.

The inherent complexities of dynamical systems often demand a computational approach to analyse the underlying physics. Developing numerical techniques pertinent to the transport process in such systems is, therefore, equally essential. The scope of this Special Issue covers, but is not limited to, the fluid flow and heat transfer problems concerning the following branches of engineering and science: aeronautical, civil, chemical, mechanical, geophysical, and oceanographic. Research contributions that broaden our understanding of thermal management devices and energy conversion techniques would also be of particular interest.

In this study, a computational thermo-fluid dynamics simulation of a wide-slot jet impingement heating process is performed. The present configuration consists of a turbulent incompressible air jet impinging orthogonally on an isothermal cold plate at a Reynolds number of around 11,000. The two-dimensional [...] Read more.
In this study, a computational thermo-fluid dynamics simulation of a wide-slot jet impingement heating process is performed. The present configuration consists of a turbulent incompressible air jet impinging orthogonally on an isothermal cold plate at a Reynolds number of around 11,000. The two-dimensional mean turbulent flow field is numerically predicted by solving Reynolds-averaged Navier–Stokes (RANS) equations, where the two-equation eddy viscosity k-ω model is utilized for turbulence closure. As the commonly used shear stress transport variant overpredicts heat transfer at the plate due to excessive turbulent diffusion, the recently developed generalized k-ω (GEKO) model is considered for the present analysis, where the primary model coefficients are suitably tuned. Through a comparative analysis of the various solutions against one another, in addition to reference experimental and numerical data, the effectiveness of the generalized procedure in predicting both the jet flow characteristics and the heat transfer at the plate is thoroughly evaluated, while determining the optimal set of model parameters. By improving accuracy within the RANS framework, the importance of model adaptability and parameter tuning for this specific fluid engineering application is demonstrated. This study offers valuable insights for improving predictive capability in turbulent jet simulations with broad engineering implications, particularly for industrial heating or cooling systems relying on wide-slot jet impingement.
