In order to eliminate the effects of scale on data obtained from a ship s model when compared to the results from the actual ship,the Reynolds similarity criterion was achieved between a scale-reduced ship model and an actual ship in numerical calculations by introduction of virtual fluid kinematic viscosity factor.
为了克服船模预报实船推进因子中的尺度效应,通过引入虚流体运动粘性系数,在数值计算中实现了缩尺船模与实船的雷诺数相似。
The identifiability of visco plastic flow coefficient γ was discussed.
对粘塑性流动系数γ的可辨识性进行了讨论，表明流动系数γ为可辨识参数；继而提出粘塑性流动系数γ的反分析数值计算方法，并编写了相应的计算程序，通过实例验算表明该方法是可行的。
