The further improvement of gas turbines requires the development of cooling techniquewith reduction of cooling air mass flow rate as well as the increase of the turbine inlettemperature. The theoretically most effective air cooling method is the transpiration cooling,which will be expected to reduce the cooling air mass flow rate. In the present study, thetwo-dimensional flow within the turbine cascade made by the porous media was analyzednumerically by the CFD code. The calculations were performed in order to examine the influenceof the porosity of the porous media on the cooling efficiency. The results revealed that thecooling efficiency was strongly influenced by the porosity of porous media.
