Aerodynamic Simulation of Turbulent Jets with Lattice Boltzmann Models
The lattice Boltzmann method (LBM) is a numerical simplification of the Boltzmann equation of the kinetic theory of gases that describes fluid motions by tracking the evolution of the particle velocity distribution function based on linear streaming with nonlinear collision. To verify the reliability and accuracy of the model simulation of incompressible fluid flow, we program to simulate two-dimensional Poiseuille flow which has the analytical solution by using the three mode: D2Q9 model, He-Luo model, Guo model (D2G9). The tests show that the guo mode gives better results.so, In the article, the Guo model is used to stimulate the jet flow field (Ma=0.2), then the result of which is compared to the result from the experience. The research of this article is the the first step to make use of the LBM on the aeroacoutics of jet flow and to provide a theoretical basis on jet aeroacoustics For further study.
