Experimental investigation on thermo‐driving heat transfer in porous medium in a centrifugal force field

Abstract

Based on the research in turbine blade super cooling techniques, experiments were carried out to investigate the thermo-driving heat transfer phenomenon in a new cooling configuration filled with porous medium in a centrifugal force field. Moreover, the heat transfer effectiveness of the configuration was compared to one with no porous medium. The results showed that the thermo-driving heat transfer effectiveness of the configuration filled with porous medium could be enhanced by increasing the rotating speed, heat flux, and cooling air speed. Meanwhile, the heat transfer effectiveness of the configuration was strengthened with the installation of porous medium.
