Experimental Research on Aerodynamic Performance in Flow Channel of Two Types of Intercoolers
The intercooler is the core component of the intercooler cycle gas turbine,and the pressure loss of air flow through the intercooler is one of the main indicators to measure the performance of the in-tercooler.In this paper,two different intercooler flow channel structures were designed,and aerodynamic characteristic tests were carried out in the two intercooler flow channels under different working condi-tions.The temperature and pressure values at different positions of the intercooler flow channel were meas-ured,and the aerodynamic characteristics of the two intercooler flow channel structures were obtained.The test results show that the total pressure loss of the intercooler mainly occurs in the turning and diffu-sing section from the inlet to the"before diversion plate",and the total pressure loss coefficient changes in a parabolic shape with the reduced flow rate,which is proportional to the inlet dynamic pressure;while the improved intercooler has a lower total pressure loss,and the total pressure loss coefficient correspond-ing to the same reduced flow rate is about 20％lower than that of the original intercooler structure.
