Physics-based turbine power models for a Variable Geometry Turbocharger (original) (raw)

This paper presents physics-based models for turbine power in Variable Geometry Turbochargers (VGTs), addressing the limitations of traditional performance maps. By utilizing the Euler turbine equations, the research develops a model that accurately reflects efficiency based on vane position, overcoming issues related to extrapolation and interpolation of existing datasheets. The proposed model aims to facilitate controlled operation in diesel engines, particularly under varying load conditions.
