Experimental Verification of Cavity-Flow Wall Effects and Correction Rules

Abstract

The report is intended as a companion to Report No. E-111A.5, 'Wall Effects in Cavity Flows', by Wu, Whitney and Lin. Some simple rules for the correction of wall effect are derived from that theoretical study. Experiments designed to complement the theory and to inspect the validity of the correction rules were then carried out in a high-speed water tunnel. The measurements on a series of fully cavitating wedges at zero angle of attack suggested that of the theoretical models that due to Riabouchinsky is superior. They also confirmed the accuracy of the correction rule derived using that model and based on a measurement of the minimum pressure along the tunnel wall.
