Blade skew plays an important role in the prohibition of propeller cavitation and needs to be analyzed quantitatively. For this purpose, the cavitation of model propellers with different skew DTMB4381, 4382, 4383 and 4384 are investigated using commercially available software Ansys-Fluent. The SST k   model was used for turbulence modeling, and the QUICK scheme was selected as the discretization scheme. The results show that present simulation is accurate and reliable for predicting the propeller hydrodynamics with cavitation. On this basis, the influences of different skew on the appearance of cavitation are analyzed. It is found that the highly skewed blade can effectively delay the occurrence of cavitation.

SPONSORIMONITOR'S REPORT Arlington, VA 22203-1995 NUMBER(S) DISTRIBUTION/AVAILABILITY STATEMENT Unlimited SUPPLEMENTARY NOTES ABSTRACTThe ultimate goal is the routine use of high-fidelity, turbulent flow modeling for the design of future waterjets. The purpose of the proposed effort is to carefully quantify the ability of a state-of-the-art homogeneous multiphase RANS solver, UNCLE-M, to predict the performance of marine propulsors over a range of cavitation numbers from single phase flow through thrust breakdown and over a variety of operating conditions. The effort is a code verification and validation effort focused on waterjet applications. During this FY computations have been completed and comparisons have been used to qualify the effectiveness of the tools to predict cavity size and shape. In addition, the tools have been used to predict cavitation breakdown performance of an as yet untested waterjet.
