Numerical Investigations on the Blade Tip Clearance Excitation Forces in an Unshrouded Turbine

The purpose of this study was to investigate the characteristics of the blade tip excitation forces represented as the rotordynamic coefficients (stiffness and damping coefficients) in an unshrouded turbine using the three-dimensional computational fluid dynamic (CFD) numerical method. The blade geo...
