GPU-BASED LATTICE BOLTZMANN SIMULATION OF A SHELL-AND-TUBE HEAT EXCHANGER

This study evaluates the use of the Implicit Large Eddy Simulation (ILES) model with the lattice Boltzmann method for simulating shell-and-tube heat exchangers. Using M-Star software on GPUs, we analyzed mesh refinement requirements and three different wall treatments. The results suggest that the wall function model is an effective approach for predicting pressure drop in industrial applications with low computational cost. This approach demonstrates significant potential for optimizing heat exchanger performance through numerical simulations.
