A projection method for combustion in the zero Mach number limit

Abstract: We present a finite difference method for solving the equations of combustion in the limit of zero Mach number. In this limit, acoustic waves are weak and do not contribute significantly to the fluid dynamics or energetics. For the equations describing this limit, we construct an efficient. high-resolution numerical method that allows for large temperature and density variations and correctly acCOl.ll1ts for expansion due to heat release.The method, a projection method, is a second order fractional step scheme… Show more

“…Subsequently, it seems that this approach was used in all the previous studies dealing with low-Mach number flows [1][2][3][4][5][6][7][8]. The approach involving a Poisson equation with variable coefficient as in Subsections 3.1 and 3.2 was preferred in [11][12][13].…”

“…The operator used in [5] used pressure defined on nodes. Lai [18] introduced a cell-centered approximate projection where pressure is defined at cell centers and which uses a standard five-point centereddifference stencil for the Laplacian. The D and G used in this report are those from [18]; a new L that also operates on cell-centered values will be defined by the FMM-PS solver.…”

“…Because the approximate projection operators are second-order accurate approximations to an exact projection, the methods that result from each choice of V are all second-order accurate for smooth problems, but not identical. The implications of these choices are discussed and analyzed in [4] for the nodal approximate projection operator [5] and the cell-centered operator [18]. For the purposes of this paper we consider versions (1) and (2) as above.…”
