| 摘 要： | 利用紧致插值曲线(constrained interpolation profile method in Zhejiang University, CIP-ZJU) 数学模型, 对低科勒冈-卡朋特(Keulegan–Carpenter) 数KC 静止流体中振荡圆柱以及雷诺数Re = 200 时流向强迫振荡圆柱绕流进行了数值模拟. 模型在直角坐标系统下建立, 采用紧致插值曲线方法作为流场的基本求解器离散了纳维-斯托克斯方程, 基于多相流的理论实现流固耦合同步求解, 利用浸入边界方法处理固体边界. 模拟结果与现有文献结果进行比较, 二者吻合情况较好, 验证了此方法对于计算复杂流动问题的可靠性.

| Abstract: | In this paper, A CIP-ZJU (Constrained Interpolation Profile method in Zhejiang University) model is developed to study a forced oscillating circular cylinder at low KC (Keulegan-Carpenter) in static fluid and flow past an in-line forced oscillating circular at Reynolds number of 200. The model was established in the Cartesian coordinate system, using the CIP method as the base flow solver to discretise the Navier-Stokes equations. The fluid-structure interaction is treated as a multiphase flow with liquid and solid phases solved simultaneously. An Immersed boundary method was used to deal with the boundary of solid body. Computations were compared with available results and good agreements were obtained, validating the reliability of the method to solve the problems of complex flow. |
