Subhash C. Mishra: Analysis of combined mode conduction and radiation heat transfer using the lattice Boltzmann method (joint with FLOW)

In the recent past, the lattice Boltzmann method (LBM) has received much attention in science and engineering as a potential computational tool for solving a large class of problems. Among many other types of problems, the LBM has been successfully used to simulate a wide range of fluid flow and heat transfer problems. Owing to its mesoscopic origin, the LBM is emerging as a versatile computational method that has many advantages. In comparison to the conventional CFD solvers like the finite difference method, the finite element method and the finite volume method, the advantages of the LBM comprise of a clear physical meaning, a simple calculation procedure, simple and more efficient implementation for parallel computation, straightforward and efficient handling of complex geometries and boundary conditions, high computational performance with regard to stability and precision, etc.

This lecture will focus on implementation of the LBM to solve energy equations of heat transfer problems involving thermal radiation in which radiative information can be computed using any of the numerical radiative transfer methods like the discrete transfer method, the discrete ordinate method, the finite volume method and the LBM. Some example problems dealing with conduction, convection and radiation heat transfer in rectangular, cylindrical and spherical geometry will be taken up to show the workability of the LBM. Implementation of the LBM on non-uniform lattices and for non-Fourier conduction cases will also be discussed.
