SCAP Spray Combustion Analysis Program.

Abstract

A computer program (SCAP) has been developed which determines the state of a propellant combustion mixture at any point along the axis of a bipropellant rocket engine. The combustion model is based upon the work of Priem and Heidmann and has been extended to treat generalized propellant and gas property data. The primary assumption of this method is that the propellant vaporization is the rate governing mechanism of the combustion process and that the vaporization of the drops can be expressed by a Ranza and Marshall type correlation. The governing equations consider mass, momentum, and heat transfer between the gas and liquid phases, and cast in one dimension. The equations are represented by a set of ordinary differential equations and are solved simultaneously using the 4th order Runge-Kutta Adams-Moulton method. This report describes the program inputs and engineering methods for the SCAP computer code. (AN)
