摘要 在内波以及其他的层结流体的实验中首先需要制备密度层结的流体,传统的双缸法只能制备密度均匀分层的层结流体。本文对传统的制备均匀层结盐水的双缸法进行改进,推导了制备任意密度剖面的层结盐水方法的理论公式以及实用数值计算方法,通过振荡圆柱实验对此方法的可行性进行了验证。 The premise of internal waves' experiments or other experiments in stratified fluid is preparation of density-stratified fluid.There is a limit in conventional "double-tank" method which can only prepare uniformly density stratified fluid.This paper improves the "double-tank" method,derive the equation and the numerical method,so that the fluid with arbitrarily density profile can be made.The feasibility of this method is tested by oscillating cylinder experiments.
