TURBULENT SEPARATION AVOIDANCE FOR TAIL-LOADED FULLY CAVITATING HYDROFOIL SECTIONS

This paper presents a method for prescribing pressure distributions which use a Stratford pressure recovery on parts of the wetted surfaces of fully cavitating hydrofoil sections. These pressure distributions are then used in an inverse design method at the ideal attack angle (shockless entry). Such pressure distributions are most useful for tail-loaded profiles because they permit the most rapid pressure rise possible with an attacked turbulent boundary layer. Examples are presented which show that very rapid pressure rises can be employed for such profiles. It is concluded that one can design practical profiles which have heavily loaded trailing edges without inducing turbulent separation.
