Abstract: Offdesign performance is of key importance now in the design of automotive turbocharger turbines. Due to automotive drive cycles, a turbine that can extract more energy at high pressure ratios and lower rotational speeds ...

Abstract: Turbocharger performance maps used for the matching process with a combustion engine are measured on test benches which do not exhibit the same boundary conditions as the engine. However, these maps are used in engine ...

Abstract: The measured performance maps of turbochargers (TCs), which are commonly used for the matching process with a combustion engine, are influenced by heat transfer and friction phenomena. Internal heat transfer from the hot ...

Abstract: Turbochargers develop away from an auxiliary component—being “off the shelveâ€‌—towards an integrated component of the internal combustion engine. Hence, increased attention is paid to the accuracy of the measured ...

Abstract: A major portion of the development of an automotive powertrain system is devoted to robustness and durability testing to ascertain the viability of the design. For turbochargers, thermo-mechanical fatigue is often considered ...
