Flow characterisation of transpiring porous media for hypersonic vehicles

Abstract:

This paper experimentally examines the internal and external flow characteristics of porous zirconium diboride (Z rB2), an Ultra-High-Temperature-Ceramic (UHTC) and a potential candidate for transpiration cooling of hypersonic vehicles. This is performed for both partially sintered material and fully densified material with cast features. The Darcy and Forchheimer permeability coefficients of these samples are determined using an ISO standard test rig. The outflow of the transpiring porous sa...
