The Design and Performance of Three 4:1 Pressure Ratio IFR Turbine Rotors 820325

Single stage turbochargers capable of producing boost pressure ratios of 4:1 or higher offer many advantages such as low unit cost, simple and compact installation and relatively a high figure of reliability. However, published data on single stage high pressure ratio turbochargers are scarce. In this paper the design and performance of three inward flow radial turbine rotors are described. The rotors were designed for 4:1 stage pressure ratio.
