Parallel Computing of Transonic Cascade Flows Using the Lattice-Boltzmann Method

Abstract

This chapter develops a lattice-Boltzmann (LB) model capable of simulating turbo-machinery flows. In the past, LB method has not been applied to turbo-machines because of its Mach number limitations and inability to handle complex geometries effectively. In the recent work, one has successfully developed a high Mach number LB model that is capable of shock capturing. In the current paper, one concentrated on establishing the capability of handling complex geometries. To demonstrate the new capability, a simulation of transonic cascade flows by the compressible LB model is performed and reported here. The parallelization and parallel efficiency of the scheme is also discussed in this chapter.
