description The results of study concerning energy transformation within the variable geometry nozzle of a turbocharger are presented in this paper. A detailed analysis is carried out in order to study the effect of losses on the permeability characteristics of the vaned channel, and to observe the flow-turbine structure interaction resulting at the rotor. Particular attention is paid to the local jet structure at outlet from the variable geometry channel when sonic conditions are likely to be reached at the diffuser throat. A supersonic flow layer can be observed in the mixing zone at the rotor inlet, this phenomenon generates high losses in this region.
