Abstract

In the last five chapters, we considered mainly the flow of a mixture of two phases of matter. In the next two chapters, we will consider some second groups in which the interaction between two phases of matter is through their interface. One of the most interesting liquid-gas problems is ablation which is a process of absorbing heat energy by removing surface material, either by melting (possibly accompanied by evaporation of the molten material) or by sublimation. Ablation has been extensively investigated during the last ten years because it is one of the important methods to protect the surface of a space vehicle from over-heating. The methods of protection of re-entry vehicles from extreme thermo-chemical environment may be divided into four categories:
  1. (i)

    Radiator

     
  2. (ii)

    transpiration cooling

     
  3. (iii)

    heat sink and

     
  4. (iv)

    ablation.
