实验表明,稀薄聚合物溶液的流动即使在低速时也会变得湍急。用数值模拟的方法研究了这种所谓的弹性湍流的形成机理,数值模拟的条件与实验条件尽可能接近,聚焦了实验上难以直接测量的数据。用一个简单的边界条件进行的初步模拟提供了对这一机制的见解。然而,在与实验类似的边界条件下,在我们的浸没边界方法的模拟中,流动不会变成湍流。
英文摘要
Flows of dilute polymer solutions are shown experimentally to become turbulent even at low speeds. The mechanism of this so-called elastic turbulence is studied via numerical simulation with conditions as close as possible to those of the experiments by focusing data which are hard to directly measure experimentally. Preliminary simulations with a simple boundary condition provide insights on the mechanism. However, with a similar boundary condition to the experiments, flows do not become turbulent in our simulations with an immersed boundary method.
