Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.
Mixed convection heat transfer in two-dimensional lid-driven rectangular cavity filled with air (Pr =0.71) is studied numerically. A hybrid scheme with multiple relaxation time Lattice Boltzmann Method (MRT-LBM) is used to obtain the velocity field while the temperature field is deduced from energy balance equation by using the Finite Difference Method (FDM).
The main objective of this work is to investigate the model effectiveness for mixed convection flow simulation. Results are presented in terms of streamlines, isotherms and Nusselt numbers.
Excellent agreement is obtained between our results and previous works. This comparison demonstrates the robustness and the accuracy of our proposed approach.
