An Analog Computer Simulation of a Closed Brayton Cycle System

Abstract

A summary of the Mathematical Model, Analog Computer Simulation, and experimental information comparison of a representative Closed Brayton Cycle System is presented. The foundation of the simulation, are design, experimentation, and analysis efforts performed on full-sized Closed Brayton Cycle System components. The analog computer program shows total system interaction and component behavior, both steady-state and dynamic modes, over the entire system operating range. In order to accurately describe a complete Closed Brayton Cycle System, practical details such as auxiliary components, system parasitic losses, variation of thermodynamic properties, thermal inertia, variability of pressure losses, and transient disturbances constitute an important part of the formulation. The development of the analog computer simulation provides an economical and effective method for system performance prediction, identification of critical parameters, systems integration, and component optimization.
