Numerical Simulation of Active Thermionic Heat Protection in High-Entalpy Flow around a Multilayered Shell

详细

A mathematical model of the process of unsteady heat transfer of a thermionic thermal protection system during convective heating is presented. The effect of the evaporation (emission) of electrons from the surface of the emitter on a decrease in its temperature is studied. It is shown that the some coolants in the composite shell affects the heat-transfer modes of active thermal protection. The calculation results qualitatively agree with the known data.
