Multiscale lattice Boltzmann schemes with turbulence modeling
The viability of multiscale lattice Boltzmann schemes for the numerical simulation of turbulent flows is discussed and numerically demonstrated for turboaxial machine applications. The extension of boundary-fitting formulas based on wall functions is proposed, which enables the efficient computation of turbulent Rows in complex curvilinear geometry using a simple Cartesian grid. Examples of two-dimensional turbulent Rows in an axial compressor cascade are presented. (C) 2001 Academic Press.
