RANS를 활용한 경사류 프로펠러의 단독성능 해석

Abstract

The present work is aimed to investigate the feasibility of the numerical prediction for the open water characteristics of the propeller in oblique flow by using RANS solver. For the verification of the numerical methods, the open water characteristics of the propeller in the PPTC (Potsdam Propeller Test case) were numerically analyzed at uniform and oblique flow conditions, which were provided as the benchmark cases in SMP’2011 and SMP’2015. The numerical results were compared with the experimental data to show good agreement. In order to investigate the POW characteristics under various oblique flow conditions, the KCS propeller (KP505) was selected as the target propeller. For various incidence flow angles (0°,5°,10°,30°,45°), the change of force and moment of the propeller were numerically investigated according to the change of the advance coefficients (0.2<J<0.9).
