Componentization of Thermo-Fluid Coupling Simulation Based on LBM

The solution of the collision-propagation equation plays an important role in the thermal-fluid multi-physics coupling simulation. Through the collision-propagation operation of different physical quantities, LBM can integrate physical fields such as fluid and thermal into the same framework to achieve coupling solution. In this paper, the collision-propagation equation is realized through LBM, and the simulation process is further componentized to improve the efficiency and reusability of the simulation. The specific component library includes: the main control module, geometric modeling of simulation field, simulation parameter setting, simulation computing, and visualization component. In LBM, since the particle motion on each lattice is independent, the componentized approach makes it easier to assign simulation tasks to multiple processors or compute nodes, thereby increasing computational efficiency.
