Abstract

Abstract: In computational fluid dynamics (CFD), the lattice Boltzmann Method (LBM) has become the mainstream method of fluid numerical simulation based on Navier-Stokes equations. The visualization of numerical results and the real-time rendering of fluid animation could provide a visual method for data analysis. A velocity field drawn method for two-dimensional visualization was proposed based on LBGK equation and D2Q9 model design algorithm model, transforming floating-point fluid velocity value into the intensity values, which was used by the RGBA color rendering method. For three-dimensional visualization, Particle Level Set Method (PLSM) was used to track the fluid surface and coupled it with LBM algorithm. Through the simulation instances, the results show the method is simple, real-time, and the fluid animation is vivid and accurate.
