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.
