Abstract
A method of operating a variable geometry turbine (VTG) during transient operations for maximum response by determining the VTG area at the balance condition of the pressure ratio and efficiency curves for the variable geometry turbine to achieve maximum power. The method includes measurements of turbine inlet pressure, turbine outlet pressure, turbine rpm, and other parameters used to measure turbine mass flow.
