不同线圈布置比例的ALIP泵模拟与流动分析
|
摘要
圆柱直线感应泵(ALIP)是以洛伦兹力为动力推动液体流动的泵送装置。本文创建了二维轴对称的单侧线圈模型泵(SS泵)和内外侧线圈布置比例为1 (DS1泵)和0.5 (DS2泵)的双侧模型泵,并进行模拟计算。结果表明,大流量工况下DS2泵内速度分布最均匀,小流量工况下DS2泵80%的速度比DS1泵分布平稳。不同流量工况下洛伦兹力分布不均匀,磁感应强度的斜率改变致使洛伦兹力产生波峰,DS2泵可改善这种不均匀。本研究表明DS2泵可有效提高流动的均匀性。
Annular linear induction pump(ALIP) is a liquid metal pump forcing by Lorentz force.In this paper, two-dimensional axisymmetric models were simply created including a single winding model pump(SS pump) and double winding model pumps, a coil arrangement ratio of 1(DS1 pump)and a coil arrangement ratio of 0.5(DS2 pump). The results show that the radial distribution of velocity in DS2 pump is the most uniform in the large flow rate, and the velocity distribution of DS2 pump in 80% is more uniform than that of DS1 pump. Under different flow conditions, the distribution of Lorentz force is not uniform. The change of slope in the magnetic flux density causes the humps of Lorentz force where is improved in DS2 pump to some degree.This paper shows that the uniformity of flow is effectively improved when the coil arrangement ratio is 0.5 in DS2 pump.
