• 目的：LBM parallel和流固耦合算法学习

    简介: 学习github上的一个开源算法LIFE:A parallel lattice Boltzmann-immersed boundary-finite element (LIFE) solver for fluid-structure interaction. 它是基于LBM方法的流固耦合算法，整体算法通过C++语言编程实现。研究方法利用LBM进行流体域的计算，FEM方法进行刚体域的计算，最后通过IBM作为过渡，使得欧拉网格的流体和拉格朗日网格的固体相互通信。结合LBM仿真，考虑压气机叶片细长结构，可以从二维不稳定的流动的角度对其进行建模。
