Heat transfer in rotating cavity with axial throughflow of cooling air

  • A test model of four co-rotating disks was developed as the simplified version of a typical internal cooling system of a gas turbine compressor. The investigation was on the distribution of local heat transfer coefficient and the averaged nusselt number of the downstream main disk. Experimental analysis may lead to following conclusions:the distribution is not of monotony and multi-peaks were found along the disk surface, u increases with the decrease of the rotational reynold number ( Re w), u increases with the axial reynold number ( Re ) and the grasholf number ( Gr ).
