本期论文广场栏目中,叶轮背叶片对离心泵内部流场的影响一文,研究了叶轮背叶片对离心泵内部流场的影响,建立了前弯、后弯和直型三种不同背叶片数量的叶轮模型,在相同工况下对离心泵内部流场进行了数值模拟。研究表明,在不同背叶片数目和形式下,泵的效率有所不同。小孔在压力容器中的设计与应用、超压低温绝热液氧容器的开
In this paper, the article column, the impeller blades on the internal flow field of the centrifugal pump, the impact of the impeller blades on the internal flow field of the centrifugal pump, the establishment of the front curve, back and straight three different number of back The impeller model was used to simulate the flow field inside the centrifugal pump under the same conditions. Studies have shown that the efficiency of the pump varies with the number and form of the different bracts.
