Application of CFD in predicting performance of high-speed planing hulls

YI Wen-bin;WANG Yong-sheng;LIU Cheng-jiang;PENG Yun-long;College of Power Engineering,Naval Univ. of Engineering;  
In order to solve the problem of unreasonable water distribution at planing hulls in numerical simulation,VOF interface interpolation scheme and mesh types are studied and several measures are proposed to improve the capabilities of FLUENT,CFX and STAR-CCM+in predicting the performance of planing hulls.With the same hexahedral mesh and simulation setting,geo-reconstruct gives the best prediction in resistance and water distribution at planing hull,while HRIC gives the worst prediction.Suitable mesh type and mesh density could also improve the performance prediction.To improve the prediction accuracy,tetrahedral mesh should be used in CFX and polyhedral mesh should be used in STAR-CCM+.It′s advisable that suitable mesh type and mesh density or georeconstruct scheme should be adopted to improve the capabilities of CFD codes in predicting the performance of planing hulls.
