摘要
先对NACA0010系列的5种最大相对厚度位置不同的翼型分别在GAMBIT中进行轴流泵建模,通过FLUENT软件对5个泵内部流场进行三维数值计算,通过对比分析得出,翼型最大相对厚度在弦长的50%处时对汽蚀的抑制效果最好。再选择最大相对厚度在弦长50%处,最大相对厚度不同的4种翼型,对4台泵进行同样的计算,可以得出最大相对厚度为14%时泵的抗汽蚀效果最好。
At first, 5 kinds of different position of aerofoil maximum thickness belong to NACA0010 aerofoil are used to model pump through GAMBIT, the flow field inside axial flow pump is simulated by FLUENT, by comparing the volume of air bubble of pumps it can be known that the performance of anti-cavitation is the best when the maximum thickness of aerofoil at 50% of chord. Secondly, 4 kinds of aerofoil that the maximum thickness of aerofoil at 50% of chord and the maximum thickness is different, the same program be done and the conclusion is that the volume of air bubble of pump is minimal when the maximum thickness of aerofoil is 14% of chord.
