Abstract:

Based on the research of turbine blade super cooling technology, the porous medium was installed in a new kind of cooling configuration with cooling tunnels. Numerical simulations were carried out to investigate the thermally driven in the new kind of cooling configuration in a centrifugal force field. The results of experiments and numerical simulations were basically consistent. The results showed that the thermally driven happened after porous medium was installed in a new kind of cooling configuration. Furthermore, the fluid and heat transfer processes were found in enclosure through fluid and temperature field gained by numerical simulations.

Key words: porous medium, thermally driven, centrifugal force field, numerical simulation, enclosure
