Summary

This special issue is dedicated to the computational and numerical advances made in heat transfer mechanisms and techniques in recent years. Heat transfer (convection, free convection, and forced convection) in different models, namely square cavities, rectangular cavities, pipes, conduits, and other such configurations, is of great significance in industrial and engineering fields. It is becoming considerably more effective in the heat transfer field to adopt new methodologies and tools, such as commercial software such as COMSOL Multiphysics, OpemFoam, and Ansys Fluent, to investigate and discuss heat transfer phenomena.


Advances in numerical methods to elucidate flow and heat analysis are also the main focus of this special issue. Numerical methods such as the shooting method, finite difference schemes, Keller box method, Homotopy Analysis Method, Optimal Homotopy Analysis Method, and Bvp-4c technique have been used to carry out analysis of different flow problems. These methods are of key significance to investigate convection, heat transfer, radiative heat, and mass transfer, as well as to analyse the Newtonian and non-Newtonian fluid models.


 In recent years, mathematicians have made significant advances with computational tools to examine different fluid flow problems. Such a significant approach is to employ neural networks, or artificial neural networks. ANN has been extensively employed by mathematicians to simulate heat transfer in distinct flow regimes. This special issue also focuses on the advances made in this area by examining heat transfer in Newtonian and non-Newtonian fluid models.

    Effects of Viscous Dissipation and Periodic Heat Flux on MHD Free Convection Channel Flow with Heat Generation

    Mustafa Abdullah
    Frontiers in Heat and Mass Transfer, DOI:10.32604/fhmt.2024.046788
    (This article belongs to this Special Issue: Computational and Numerical Advances in Heat Transfer: Models and Methods I)
    Abstract This study investigates the influence of periodic heat flux and viscous dissipation on magnetohydrodynamic (MHD) flow through a vertical channel with heat generation. A theoretical approach is employed. The channel is exposed to a perpendicular magnetic field, while one side experiences a periodic heat flow, and the other side undergoes a periodic temperature variation. Numerical solutions for the governing partial differential equations are obtained using a finite difference approach, complemented by an eigenfunction expansion method for analytical solutions. Visualizations and discussions illustrate how different variables affect the flow velocity and temperature fields. This offers comprehensive insights into MHD flow behavior… More >

    Thermal Radiation Effects on 2D Stagnation Point Flow of a Heated Stretchable Sheet with Variable Viscosity and MHD in a Porous Medium

    Muhammad Abaid Ur Rehman, Muhammad Asif Farooq, Ahmed M. Hassan
    Frontiers in Heat and Mass Transfer, DOI:10.32604/fhmt.2023.044587
    (This article belongs to this Special Issue: Computational and Numerical Advances in Heat Transfer: Models and Methods I)
    Abstract This paper proposes a mathematical modeling approach to examine the two-dimensional flow stagnates at x = 0 over a heated stretchable sheet in a porous medium influenced by nonlinear thermal radiation, variable viscosity, and MHD. This study’s main purpose is to examine how thermal radiation and varying viscosity affect fluid flow motion. Additionally, we consider the convective boundary conditions and incorporate the gyrotactic microorganisms equation, which describes microorganism behavior in response to fluid flow. The partial differential equations (PDEs) that represent the conservation equations for mass, momentum, energy, and microorganisms are then converted into a system of coupled ordinary differential… More >

    An Efficient Approach for Solving One-Dimensional Fractional Heat Conduction Equation

    Iqbal M. Batiha, Iqbal H. Jebril, Mohammad Zuriqat, Hamza S. Kanaan, Shaher Momani
    Frontiers in Heat and Mass Transfer, Vol.21, pp. 487-504, 2023, DOI:10.32604/fhmt.2023.045021
    (This article belongs to this Special Issue: Computational and Numerical Advances in Heat Transfer: Models and Methods I)
    Abstract Several researchers have dealt with the one-dimensional fractional heat conduction equation in the last decades, but as far as we know, no one has investigated such a problem from the perspective of developing suitable fractionalorder methods. This has actually motivated us to address this problem by the way of establishing a proper fractional approach that involves employing a combination of a novel fractional difference formula to approximate the Caputo differentiator of order α coupled with the modified three-point fractional formula to approximate the Caputo differentiator of order 2α, where 0 < α ≤ 1. As a result, the fractional heat… More >

    Frontiers in Heat and Mass Transfer, Vol.21, pp. 523-537, 2023, DOI:10.32604/fhmt.2023.045914
    (This article belongs to this Special Issue: Computational and Numerical Advances in Heat Transfer: Models and Methods I)
    Abstract This work presents a simulation of the phenomena of natural convection in an enclosure with a variable heating regime by the lattice Boltzmann method (LBM). We consider a square enclosure of side H filled with air (Pr = 0.71) and heated from below, with a hot portion of length L = 0.8 H, by imposing a sinusoidal temperature. The unheated segments of the bottom wall are treated as adiabatic, and one of the vertical walls features a cold region, while the remaining walls remain adiabatic. The outcomes of the two-dimensional (2D) problem are depicted through isotherms, streamlines, the temperature evolution… More >

    Frontiers in Heat and Mass Transfer, Vol.21, pp. 539-562, 2023, DOI:10.32604/fhmt.2023.043023
    (This article belongs to this Special Issue: Computational and Numerical Advances in Heat Transfer: Models and Methods I)
    Abstract The purpose of this research is to investigate the influence that slip boundary conditions have on the rate of heat and mass transfer by examining the behavior of micropolar MHD flow across a porous stretching sheet. In addition to this, the impacts of thermal radiation and viscous dissipation are taken into account. With the use of various computing strategies, numerical results have been produced. Similarity transformation was utilized in order to convert the partial differential equations (PDEs) that regulated energy, rotational momentum, concentration, and momentum into ordinary differential equations (ODEs). As compared to earlier published research, MATLAB inbuilt solver solution… More >
