Abstract

Based on the exploiture of turbine blade super cooling technology, porous medium is installed in a new kind of cooling configuration with cooling tunnels. Experiments and numerical simulations are carried out to investigate the thermally driven heat transfer rules in the new kind of cooling configuration with different porosity 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 porosity. 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 can be weakened with increase of the porosity under high porosity.
