| Abstract: | The grids of a cylinder filled with internal fluid and four kinds of grids of heat exchanger square arrays full of external fluid around it are built, and the material and geometric parameters are set intelligently by using the Ansys parametric design language (APDL) in the Ansys software. Dynamic characteristic is calculated by the fluid-solid interaction analysis. By means of analysis of calculated results, some useful conclusions are given, which may be used as the references for designing of heat exchanger and chemical equipments. |
