Analysis on Impact of Heat Transfer on Turbocharger Efficiency Performance
Abstract：There is a heat transfer from turbine to compressor through the housing due to tem- perature difference between the hot turbine and the relatively cold compressor when efficiencies of the turbine and the compressor are measured on a hot gas test bench. Generally heat transfer falsifies the turbine efficiencies to higher values and the compressor efficiencies to lower values. The heat transfer is investigated and an effective method is applied for efficiency correction of turbine and compressor. The efficiency results after correction complies perfectly with the measurement values from cold test bench for turbocharger with maximum difference below 4.7%.
