PARC Code: Theory and Usage

Abstract
The PARC code is a general purpose flow simulation computer program. It is based on the NASA Ames-developed ARC code and has been extensively enhanced for usage in an applications-oriented environment. A wide variety of flows may be simulated, including those with complex geometries (e.g., aircraft forebody and inlet in a wind tunnel) and those with complex fluid dynamics (e.g. , turbulent wall jet). Flow simulations may be two-dimensional, axisymmetric, or three-dimensional; also, they may be inviscid, laminar, or turbulent. Generalized boundary conditions may be located anywhere within the computational grid. Flow geometries may be treated by blocks so that the grid-generation process is simplified, and very complex problems may be simulated. This flow- simulation program has proven to be a very versatile and robust tool for the analysis of engineering problems involving fluid flows.
