Experimental Methods for Evaluating Components of Turbomachinery, for Use in Automotive Fuel Cell Applications

This paper describes methods and test beds for components of turbomachinery, use in automotive fuel cell applications at the Ostfalia University applied sciences. Turbomachinery is subject to different requirements than those conventional turbochargers. Therefore, turbine air bearings an electrical turbocharger will be evaluation. The boundary conditions comparison turbochargers, with less heat high humidity from cell, are especially interest. Air affect friction vibrations/oscillations shaft. need fulfill these types turbomachinery. bed modified a new coupling solution, ensure that driving electric motor combination shaft component complies strict tolerances. For this, magnetic coupling, high-speed applications, developed tested on bed. was adapted hot gas extended maps determined. To reach application, water injection system integrated into
