A literature review was made of the various theories proposed and the experimental results obtained in the field of transpiration cooling of turbulent boundary layers. The over-all objective of the review was to examine the extensive literature pertaining to transpiration cooling and to access the state of the art of this cooling scheme in the following subject areas 1 the theoretical analyses pertaining to the correlation of mass injection rates with surface temperature 2 the experimental investigations relating to the verification of existing theories and the development of empirical correlations for determining the effects of mass injection on surface heat transfer and skin friction 3 the theoretical and experimental studies regarding the characteristics of, and flow through, conventional porous materials.
