When operating a turbocharger with an engine the turbine transfers a considerable amount of heat to its environment and to the compressor. Therefore the flow processes in the turbine as well as in the compressor are strongly diabatic. The definition and the experimental determination of turbine and compressor efficiency require a clear distinction between adiabatic and diabatic efficiencies since the heat flux between turbine and compressor must be taken into account. The influence of the heat flux between turbine and compressor on the compression process was studied at two turbochargers for passenger cars of different design. The essential difference of the two turbochargers is the arrangement of turbine and compressor, because the type of bearing is different for each charger. While one turbocharger has sliding bearings, the other charger exhibits roller bearings. The experiments were performed with hot and cold operation of the chargers. The results of the measurements show that the heat flux transfered from the turbine to the compressor and thus the compressor exit temperature depends to a large extent on the mechanical design of the turbocharger.
