| Abstract: | Transpiration cooling is an important means of thermal protection. A transpiration
control model is presented in this paper. By malting use of heat balance of finite
elements in variable domain a differential equation of control has been derived. Numerical
calculation of the equation is performed with ammonia used as coolant under nonablation
condition.The result shows that this mathematical model exactly agrees with
the true physical process and provides a numeral basis for the theoretical research of
this type of distributed parameter systems. |
