Flowing Rule of Viscoplastic Fluid in More Layer Medium 粘塑性流体在分层介质中的流动规律
MR fluid has its unique property: It can become from Newton flu-id to viscoplastic fluid under the action of strong magnetic field, the rheological fluid damper has the advantages of simple structure, small volume, reversible and continuous work and less energy consumption. MR流体具有的独特性质在于:在强磁场的作用下,可由牛顿流体变为粘塑流体,而变液阻尼器则具有结构简单、体积小、工作连续可逆,能耗小等优点。
The model provides the basis for the numerical simulation for the work process of the working chamber earth pressure system. ( 2) The pressure dependent viscosity model and density model of viscoplastic non-newtonian fluid is established by user-defined method in CFD simulation environment. 提出了CFD仿真环境下非牛顿流体压力相关的粘度模型及密度模型的自定义方法,实现了对EPB盾构密封舱土压力系统工作过程中改性土体粘-弹-塑性流动行为的数值模拟。
