Conjugate Heat Transfer for a 2D Square Cylinder Using Lattice Boltzmann Method

In this study, we model an unsteady conjugate heat transfer problem of a solid square cylinder confined in a straight channel with adiabatic walls. In modeling of the problem, we use an in-house developed Lattice Boltzmann solver that can run on GPU. To validate the solver, we compare the obtained results with the data from two previous studies that are available in the literature by considering pressure distribution on the cylinder and spatially averaged Nusselt number along the cylinder edges. The results are in good agreement in general and promising for future studies to reveal unsteady and complex nature of the problem.
