Numerical method for two-dimensional unsteady reacting flows
Abstract
A method that numerically solves the full two-dimensional, time-dependent Navier-Stokes equations with species transport, mixing, and chemical reaction between species is presented. The generality of the formulation permits the solution of flows in which deflagrations, detonations, or transitions from deflagration to detonation are found. The solution procedure is embodied in the RICE computer program. RICE is an Eulerian finite difference computer code that uses the implicit continuous-fluid Eulerian technique to solve the governing equations. The differential equations of motion and the solution procedure of the RICE program are stipulated. Next, a method is described for artificially thickening the combustions zone to dimensions resolvable by the computational mesh. Finally, the results of two example calculations are presented.
