In the twodimensional wind tunnel , systematic experimental researches were carried out on the phenomenon of reverse transition on a heated plane with stable density stratification 针对加热平板表面密度分层结构中的逆转捩现象,在二元风洞中进行了系统的实验研究。
Some examples are given , showing that density stratification can have a large effect on the added mass and damping of the floating rectangular box in a two - layer fluid over a range of frequencies 对所建立的求解模型进行了数值计算分析,结果表明在矩形箱浮体的某个振荡频率范围内,流体的分层效应对其附加质量和阻尼系数有显著影响的。
The results are compared with the cases in a single - layer fluid , showing that the density stratification can have a relative large effect on the drag and lift coefficients as well as the vortex shedding 计算受迫振荡圆柱体的升力系数、阻力系数随时间的演化曲线和圆柱体的尾涡分布,以及圆柱体的受迫振荡激发两层流体内界面的扰动,并与均匀流体的情况进行了比较分析。
