论文摘要
研究了由于排放电池电极和环境空气之间的温度梯度引起的对流流量的影响，以进行平行板电极排列。结果表明，放电操作期间温度的升高会导致排出间隙中MD数的增加。在较高的热梯度下，对流气流速度也增加，MD通道遵循气流方向。对流流的速度通过CFD模拟估算，并将其与通过粒子图像速率法获得的MD通道的平均速度进行了比较。
The impact of convective flow due to the temperature gradient between discharge cell electrodes and ambient air was studied for parallel-plate electrode arrangement. It was shown that an increase in temperature during the discharge operation leads to an increase in MD number in the discharge gap. The convective gas flow velocity also increased at a higher thermal gradient, and MD channels follow the gas flow direction. The velocity of convective flow was estimated by the CFD simulation and compared with the mean velocity of MD channels obtained by the particle image velocimetry method.
