Abstract
Based on the flow field numerical calculation, the three-dimensional turbulent flow of the centrifugal pump has been numerically calculated by Reynolds averaged N-S equations by using the RNG turbulent model and the SIMPLEC algorithm. The head, shaft power and efficiency at five different operating points are predicted by using numerical calculations at the design flow rate in the range of 0.6-1.4 times. The performance curves were drawn according to the calculation results, which were consistent with the performance curves obtained from the experiment. Through numerical calculation, the velocity and pressure distribution of the inner flow field of the centrifugal pump are obtained and analyzed. The internal flow phenomena and rules of the centrifugal pump are revealed. The calculation case shows that the 3-dimensional turbulent numerical calculation provides the theoretical basis for centrifugal pump structure optimization and performance prediction. The method shows a certain academic value and practical significance.
