确定形状因子的修正的Prohaska方法

A corrected Prohaska method for determining hull form factor

在Ｈｕｇｈｅｓ和Ｐｒｏｈａｓｋａ关于阻力成分的基本假定下，通过求解描述粘压阻力同总阻力系数之间关系的方程组求得到形状因子１＋Ｋ，从而不仅提高了预报精度，而且保证了计算结果的可靠性．

A corrected method of determining hull form factor 1+K is presented. Thefoundation is also derived from the assumption given by Hughes and Prohaska,but the solution of1+K can be obtained from the analytical relation between coefficients of total and of viscous-pressure resistance. In comparison with Prohaska's method the value of hull from factor isstationary and reasonable as applying all of information for resistance test results to thecomputatlon.
