Pressure Projection Method in Generalized Coordinates

Part of the Scientific Computation book series (SCIENTCOMP)


In Chapter 2, a general idea of the pressure projection method is introduced. This method is described in detail for developing general three-dimensional simulation capability. While an artificial compressibility approach modifies the nature of governing equations, the pressure projection method is formulated time accurately, and so is used both in time-dependant problems and for obtaining steady-state solutions. In light of successful computations in Cartesian coordinates using its numerous variants, Rosenfeld et al. (1991a, b, 1992) developed a staggered grid-based fractional step method in general curvilinear coordinates. Later, Kiris and Kwak (2001) developed a more robust implicit procedure for “not- so-nice” grids using the same finite-volume framework. Among many variations in projection methods, the details presented in this chapter are extracted from these activities by the authors and their colleagues at NASA Ames Research Center.
