【 摘 要 】

The compressor adiabatic performance map is important for turbocharger matching with engine. Its accuracy was affected by the heat transfer phenomenon in the turbocharger. The corrected method for compressor performance measurement which affected by heat transfer was widely investigated by some authors. The aim of this work was to measure compressor adiabatic efficiency by simplified method, and estimated the effects of internal heat transfer on compressor efficiency. This approach only added five temperature sensors on the turbocharger based on the standard instruments and doesn't need other special instruments, and the heat transfer properties of turbocharger and compressor adiabatic efficiency could be calculated by lumped model. This method was validated by other experiments. Finally, the heat absorbed by compressor under different operating conditions was analyzed by this method. The results showed water-cooling was main influenced factor, and water-cooling was a barrier for heat transfer from turbine to compressor.
