CAN SHAPES WITH NEGATIVE PRESSURE GRADIENTS PREVENT CAVITATION?

摘要

Axisymmetric and plane shapes with negative pressure gradients at a surface are calculated. It is shown that the length of the pressure increase zone may be very short. The axisymmetric bodies tested in a wind tunnel with a small obstacle placed on the surface provide unseparated flow patterns. The discussed shapes may probably be used for the prevention of cavitation.
