An Experimental and Theoretical Investigation of a Twin-Entry Radial Flow Turbine under Non-Steady Flow Conditions 801136
One of the methods of representing a turbocharger-turbine in the exhaust system of internal combustion engines is by assuming quasi-steady flow at turbine boundaries, while taking into account the generation of pressure waves both upstream and downstream of the turbine due to non-steady flow conditions.
This method relies substantially on steady flow turbine characteristics for the generation of boundary conditions. A method is presented to allow for wave action both upstream and downstream of a twin-entry radial inflow turbine. The method also allows for different flow rates in each entry to simulate the partial admission condition. Comparison is made between experimental results and theoretical analysis.
