Parametric study of the aerothermodynamics of a jet engine test facility

Abstract

A three-dimensional numerical analysis of the Jet Engine Hush House located at Naval Air Station Jacksonville, Florida was developed using the PHOENICS computer code. The PHOENICS code was used to determine the steady state aerothermal characteristics in the Hush House produced by a Navy F-4 (Phantom II) J-79-GE-8 gas turbine engine with afterburner. The PHOENICS generated pressure, velocity, and temperature fields of the test cell facility based on the k-epsilon turbulence model are compared with results generated by a model incorporating a temperature dependent kinematic turbulent viscosity. In addition, for the k-epsilon turbulence model, the effect of augmenter tube length on system behavior was investigated. Lessons learned and recommendations in obtaining a converged solution are included to aid in further applications of the PHOENICS code.
