实船阻力及流场数值预报方法
Numerical methods for predicting ship resistance and flow field
摘要
Abstract
This paper uses the extrapolation method based on the model-scale numerical calculation,virtual fluid viscosity method and full-scale calculation method to predict and analyze the resistance and flow field of a ship in full-scale. With the Froude number within the range of 0.15 ~ 0.41,the difference between the resistance predic-tions based on the three methods and the full-scale data extrapolated from the model-scale measurements is less than 7%,4.5%,3.5%,respectively. In addition,the virtual fluid viscosity calculation and full-scale calculation had in-cluded the effects of roughness. The virtual fluid viscosity method and full-scale calculation method gave consistent predictions of the free surface evaluation and wake field. The virtual fluid viscosity method can predict full-scale re-sistance and the flow field well with the least computation time,and as a result is useful for engineering.关键词
