Abstract

Based on the research of turbine blade super cooling technology

porous medium was installed in a new kind of cooling configuration with cooling tunnels.Experiments and numerical simulations were carried out to investigate the thermally driven heat transfer rules in the new kind of cooling configuration with different thickness of porous layers in a centrifugal force field.The results of experiments and numerical simulations are consistent basically.The results of study show that the heat transfer rules of the new cooling configuration are identical under different thickness of porous layers.The thermally driven heat transfer of the cooling configuration filled with porous medium can be enhanced with increase of the rotate speed

heat flux and cooling air speed.At the same time

the heat transfer effect is weakened with increase of the thickness of porous layer.
