| 摘 要： | 通过对等离子点火器阳极冷却水通道内的流场进行数值模拟,得到了不同冷却水进出方式、不同冷却水的流量及不同冷却通道长度时阳极表面的温度场,通过比较阳极冷却表面温度得出结论:随着进口冷却水流流量的增加冷却效果越好;随着冷却通道的长度增加冷却效果越来越好;上进侧出冷却水进出方式为最优方式。

| Abstract: | The temperature fields of anode have been obtained by numerical simulation of anode cooling duct inner of the plasma ignition device with different cooling water velocity,cooling duct length and the way of cooling water inflow and outflow.With comprising anode temperature of different case, the conclusion could be drawn: with water flow increased,cooling effect is better;the longer cooling duct is,the better cooling effect is;the best way of cooling water inflow and outflow is inflowing to the top and outflow from the side. |
