| 摘 要： | 利用ANSYS CFX有限元程序建立了HL-2M欧姆测试线圈和冷却水模型,应用热传导和对流换热方程建立了流固边界层,对线圈的温升和冷却进行了流固耦合计算。计算结果表明,线圈由焦耳热引起的最高温升与电流密度、等效放电运行时间有关,而冷却水流量对最高温升影响较小,冷却水流量主要决定线圈的冷却时间间隔的长度,欧姆测试线圈的最长冷却时间间隔为5min。

| Abstract: | The models of HL-2M ohmic test coil and the cooling water have been built by using ANSYS CFX finite element software,and the coil temperature rise and water cooling have been calculated by the fluid-solid coupling with the boundary of heat conduction and convective heat transfer equation.As a result,the ohmic coil maximum temperature rise caused by the joule heat,has close relationship with current density and the equivalent running time,and has little relationship with cooling water flow;cooling water flow decides mainly the length of the ohmic coil cooling time interval,maximum cooling time interval is 5min. |
