Abstract: | The suggested scaling concept for cavitation inception index takes into account boundary layer separation caused by tip vortices, as well as difference in dependencies of boundary layer thickness on Reynolds number for laminar and turbulent boundary layer. Provided asymptotic analysis gives two scaling laws with different values of power for high and low Reynolds numbers. Deduced values correspond well to known experimental data. |
