Pulse Detonation Engines Cycle Analysis and Performance Prediction Code

A transient performance PDE code is proposed for development and demonstration in this SBIR project. The proposed formulation methodology for the performance code is based upon a zero-order time-marching methodology to compute PDE properties as a function of PDE cycle time. The proposed PDE code formulation does not require shape functions from experiments or unsteady-CFD simulations, it rather computes the pressure, temperature, density, mass flow, thrust as a function of time within each PDE cycle by using a zeroth order time-marching methodology.The perfromance code will be developed in a modular manner as to allow for incorporating new improved submodels for inlet, nozzle, and PDE chamber as they become available.
