Investigation of Unsteady Aerodynamic Excitation on Rotor Blade of Variable Geometry Turbine
To investigate the aerodynamic excitations in variable geometry turbines, the full three-dimensional viscous unsteady numerical simulations were performed by solving N-S equations based on SAS SST method. The aerodynamic excitations at varied expansion ratios with six different vane stagger angles t...
