| Research Abstract |
LES (Large Eddy Simulation), which has become used for turbulent flow simulation even in turbomachines, has a problem with near-wall treatment. In order to capture eddies with different scale in turbomachines, it is suitable to apply a multi-scale analysis that changes the calculation method according to eddy scales. The goal is to develop a numerical method for such multi-scale analysis by taking advantage of the lattice Boltzmann method.
