Calibration and Results of a Radial Turbine 1-D Model with Distributed Parameters

Popis výsledku v původním jazyce

The physical 1-D model of a radial turbine consists in a set of gas ducts featuring total pressure and/or temperature changes. The model published before is amended by a semi-empiric mechanical loss and windage loss modules. The instantaneous power of aturbine is integrated along the rotating impeller channel using Euler turbine theorem. The main aim of the current contribution is to demonstrate the use of measured turbine maps for calibration of unsteady turbine model for different lay-outs of turbineblade cascades. The turbine model calibration parameters are identified by means of the same model applied to a steady flow turbocharger testbed simulation using optimization. The examples of model results at a four cylinder engine are compared to evaluation of a turbine performance at an engine. The interpolation and extrapolation of turbine parameters to different blade cascades lay-outs is carried out in dependence on turbine pressure ratio and rack positions.
