Multiscale lattice Boltzmann schemes for low Mach number flows. (English) Zbl 1001.76082

Summary: A low Mach number approximation (LMNA) of Navier Stokes equations is widely used in numerical methods for the simulation of low-speed thermal and athermal flows. The advanced lattice Boltzmann approach (Bhatnagar-Gross-Krook) for the solution of the LMNA equations is discussed, and its performance is compared with the performance of commercial CFD code FLUENT 5.
