Instantaneous On-Engine Twin-Entry Turbine Efficiency Calculations on a Diesel Engine
2005 (English)In: Powertrain & Fluid Systems Conference & Exhibition Technical Papers, 2005Conference paper (Other academic)
One-dimensional engine simulation codes are frequently used for engine development where turbine performance is in focus for overall engine performance. Turbocharger performance can today not be accurately simulated without adjustments of the turbine efficiency and mass flow multipliers. In spite of the fact that engine exhausts are dominated by unsteady pulsating flow the performance maps provided by the turbo manufacturers are measured under steady conditions and for a range that does not cover the entire turbine operating range.
