摘要
基于Fluent软件,采用标准湍流模型在其它泵体参数选用经验值的情况下,对不同面积比的环形射流泵内部流场进行了数值模拟,计算得出2种入射角度下射流泵的性能参数,分析了不同面积比对射流泵最大效率的影响。结果表明:当面积比为1/3时,射流泵效率最高。以最高效率下降3%为原则,得出最优面积比的范围为0.3～0.35之间。
Based on Fluent software, using standard model and with other parameters selecting emporical values, makes numerical simulations of the flow field of different area ratios in annular jet-pumps. Calculates the performance parameters of the jet-pump of two type injecting angles and analyses the effect of different area ratios on the efficiency. The results indicate that the highest efficiency is at the area ratio of 1/3. According to the principle of the highest efficiency reducing 3 %, the optimal area ratio is between 0.3 to 0.35.
