| description | This paper presents a numerical model intended for a system study of transpiration cooled
thermal protection systems. The code PIRATE(Porous ImpulseResponse Analysis forTranspiration
cooling Evaluation) enables rapid transient calculations for thermal protection systems
of hypersonic flight vehicles. In the code, semi-empirical aerodynamic correlations are employed.
However, the code could also be used by applying higher fidelity inputs from CFD
calculations. The wall temperature distribution is calculated by utilising the thermal impulse
and step responses of porous media, increasing the calculation speed significantly. A heat flux
balance is considered for a one-dimensional porous material. The code is validated with experimental
data of plasma wind tunnel tests and the SHEFEX II flight experiment. The transient
heating of a flat plate model in a steady state flow condition in the L2K plasma wind tunnel is
assessed for both un-cooled and transpiration cooled cases. The SHEFEX II flight simulation
accounts for transient external flow conditions and is used to assess the downstream coolant
film effect after the injection point. The trends of experimental surface temperature measurements
are replicated well by the simulations. The predicted and measured temperatures are
in good agreement and within a margin of 10 %. |
