Abstract
A PROPOSAL IS PRESENTED HEREIN TO DEVELOP A NUMERICAL PROCEDURE FOR ANALYZING THE SHIP NUMERICAL PROCEDURE FOR ANALYZING THE SHIP PROPELLER TIP VORTEX PROBLEM. THE FLOW IN THIS REGION IS VERY COMPLEX AS IT CONTAINS THREE-DIMENSIONAL, VISCOUS AND CENTRIFUGAL EFFECTS. THE LONG TERMS GOAL OF THE PROPOSED EFFORT WOULD DEVELOP A COMPREHENSIVE PREDICTIVE PROCEDURE FOR THE SHIP PROPELLER TIP REGION WITH PARTICULAR EMPHASIS ON THE TIP VORTEX CAVTATION PROBLEM. ALTHOUGH THIS LONG TERM WOULD REQUIRE A VARIETY OF EFFORTS FOCUSED UPON TURBULENCE MODELING, BLADE GEOMETRY, ROTATIONAL EFFECTS, ETC., THE FIRST PHASE AS HEREIN PROPOSED WOULD FOCUS UPON REVISINGEXISTING CODE TO INCLUDE ROTATIONAL EFFECTS, DEVELOPING A GEOMETRIC TWIST CAPABILLITY AND PERFORMING A DEMONSTRATION CALCULATION.
