Abstract

The paper attempts to correlate simulations and measurements of turbine performance under pulsating flows for automotive turbochargers. Under real automotive powertrain conditions, turbochargers are subjected to pulsating flows, due to the engine valves motions. Experiments on a purposively built 2.2L Diesel engine gas-stand have allowed quantification of unsteady pulsating turbine performance. Temperature, pressure and mass flow measurements are fundamental for the characterisation of turbine performance. Adequate sampling frequency of instruments and acquisition rates are highly important for the quantification of unsteady turbomachine performance. However, in the absence of fast responsive sensors for monitoring mass flow and temperature, appropriate considerations would have be made to perform estimates of turbine performance under pulsating flows.
