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。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.

关 键 词：HL-2M欧姆测试线圈 流固耦合 冷却时间间隔.
