Perspectives in control-oriented modeling of combustion processes in liquid rocket engines

Research output: Contribution to conferencePaper

Abstract

We develop a detailed model of the multicomponent flow, reaction, and transport processes in liquid propellant rocket combustion chambers. This model accounts for realistic chemical kinetics, two-phase flow, along with viscous and other dissipative effects. The model also allows the inclusion of a variety of actuators and sensors, as well as process and measurement disturbances. In addition to its potential usefulness to the designer in understanding the dynamical complexity of the system and the sources of model uncertainty, the model provides a rigorous basis for control system design. An appraisal of current and feasible actuators and sensors, and their mathematical representation are included. A discussion is presented of methods by which the complexity of the model might be reduced, with particular emphasis on retention of important phenomena and tractability of analysis. Finally properties of, and prospects for the use of, nonlinear acoustic models as simplified model descriptions, are discussed.
