Özet
In this study, performances of Ranque-Hilsh Vortex Tubes (RHVTs) were experimentally investigated under three different situations based on inlet pressure and the ratio of mass flow rate of the cold stream to the mass flow rate of the inlet stream (xi). 1st situation is the conventional RHVT. 2nd situation is the threefold cascade type RHVT. Here three RHVTs were used. 3rd situation deals with the six cascade type RHVT. In this case, six RHVTs were used. When all the test results under P-i = 360 kPa and P-i = 400 kPa pressure conditions are compared, it is found that the best performance occurs at the 3rd situation. Moreover, the performance of the 3rd situation at P-i = 400 kPa pressure is higher than that at P-i = 360 kPa. Maximum values of Delta T and xi are obtained as 67.6 degrees C and 0.9 for 3rd situation. (C) 2011 Elsevier Ltd and IIR. All rights reserved.
