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.

  Abstract The cavity with lid-driven is greatly used in mixing, coating, and drying applications and is a substantial issue in the study of thermal performance rate and fluid field. A numerical approach is presented to study the thermal distribution and passage of fluid in a lid-driven cavity with an upper oscillating surface and an attached baffle. The walls of a cavity at the left and right were maintained at 350 and 293 K, respectively. The upper oscillating surface was equipped with a variable height to baffle to increase the convection of the three kinds of TiO₂, Al₂O₃, and CuO nanofluids with… More >

  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, Vol.22, No.1, pp. 141-156, 2024, DOI:10.32604/fhmt.2024.046788
  （This article belongs to the 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 >

  Frontiers in Heat and Mass Transfer, Vol.22, No.1, pp. 263-286, 2024, DOI:10.32604/fhmt.2023.044587
  （This article belongs to the 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 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 equations (ODEs) through… More >

  S. H. Elhag

  Frontiers in Heat and Mass Transfer, Vol.22, No.1, pp. 377-395, 2024, DOI:10.32604/fhmt.2023.044428
  （This article belongs to the Special Issue: Computational and Numerical Advances in Heat Transfer: Models and Methods I)
  Abstract A review of the literature revealed that nanofluids are more effective in transferring heat than conventional fluids. Since there are significant gaps in the illumination of existing methods for enhancing heat transmission in nanomaterials, a thorough investigation of the previously outlined models is essential. The goal of the ongoing study is to determine whether the microscopic gold particles that are involved in mass and heat transmission drift in freely. The current study examines heat and mass transfer on 3D MHD Darcy–Forchheimer flow of Casson nanofluid-induced bio-convection past a stretched sheet. The inclusion of the nanoparticles is a result of their… More >

  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 the 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 the 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 >
