Two-dimensional material response of a transpiration-cooled system in a radiative/convective environment
Abstract
The two-dimensional unsteady material response of a transpiration-cooled system in a radiative/convective heating environment is analyzed numerically with the use of the strongly implicit procedure (SIP). The internal mass flow rate, internal pressure, and in-depth solid and fluid temperature distributions are obtained for various matrix porosities and coolant mass injection rates in a CO2/silica transpiration-cooled system. The results for application on Saturn entry vehicles provide a feasible idea for a thermal protection system in a severe radiative/convective heating environment. The feasibility of this analysis is tentatively verified by comparison with the experimental results of a radiation simulation of one-dimensional, relatively low-incident radiative heating.
