Abstract (2. Language): 
Possibilities and limitations of 1D unsteady and 3D steady flow simulations in the vane-less turbocharger turbine of a 1.7 liter SI engine is presented experimentally and numerically. To validate the results of simulation by experimental results, a test setup of the turbocharged engine on dynamometer is prepared and various performance parameters are measured at the different engine speeds. The complement form of the volute and rotor vanes are modeled. Mesh studies are done and the best them is selected and qualified by calculation of the dimensionless wall function. Two ways of modeling the rotating wheel, Multiple Frames of Reference (MFR) and Sliding Mesh (SM), are considered. Finally, the variations of performance turbine parameters are studied by pulses frequencies surveying and the present paper is concluded that the 3D unsteady flow is needed to get a good result of the turbine modeling. The results obtained here will be used in simulating three dimensional and unsteady compressible flows in turbocharger turbine which will be reported very soon
