An explicit computational fluid dynamics (CFD) computer code with parallel processing capability has been developed for the purpose of simulating internal high-speed reacting flows. The code solves the three-dimensional Navier-Stokes equations for compressible flows. The CFD code can be executed on either sequential (single processor) computers or multi-computers (multiple processor machines with distributed memory and message passing between processors). The parallel implementation involves homogeneous domain decomposition between processors with message passing needed only between neighbor processors. The code is validated for a compression ramp, an expansion ramp, a viscous flat plate, and a viscous flat plate with wall injection. These results are presented and discussed. Also, parallel timings, relative speed-ups, and relative efficiencies are presented and discussed. These preliminary results indicate that parallel processing should solve the resource and speed shortages currently encountered with sequential computers for problems of interest.
