Investigation of the Turboramjet Pre-cooler by Using a Controllable Porous Media Structure

Abstract

An analysis was conducted to investigate the flow and heat transfer of a turboramjet pre-cooler and a new concept pre-cooler used controllable octahedron porous media structure is developed. The pressure and temperature distribution of the pre-cooler is investigated with both numerical and experimental method. Additionally an optimization theory and evaluate factor of porous media structure was developed and applied into the pre-cooler optimization. At the present work the CFD results regarding the pressure drop and heat transfer performance were compared to available experimental data and were found to be in agreement. Thus, the porous media pre-cooler could be applicable to the turboramjet.
