Quasi-2D Unsteady Flow Solver Module for Rocket Engine and Propulsion System Simulations

Abstract

A new quasi-two-dimensional procedure is presented for the transient solution of real-fluid flows in lines and volumes including heat transfer effects. The solver is targeted to the commercial dynamic simulation software package Simulink(Registered) for integration into a larger suite of modules developed for simulating rocket engines and propulsion systems. A Fortran95 code using more conventional solution procedures is being developed in parallel to provide verification test cases. The solution procedure for both codes is coupled with a state-of-the-art real-fluids property database so that both compressible and incompressible fluids may be considered using the same procedure. The numerical techniques used in this procedure are described. Test cases modeling transient flow of nitrogen, water, and hydrogen are presented to demonstrate the capability of the current technique.
