Abstract

In order to make the axial pump has improved performance, it is important to distinguish regarding the flowing distributions. According to the Navier–Stokes equations (NSE), Standard k − ϵ turbulence model and algorithm of SIMPLE, the CFD technique investigation is applied of the three dimensions flow passage in pump using the sliding mesh approach (SMA). The structural of numerical unsteady flow simulation and behaviour transient dynamic study of an axial pump is carried out at various conditions depend on the method of fluid-structure interaction. Numerical outcomes reveal that the higher-pressure distribution of axial impeller happens at the outer impeller diameter closed to the tip blade region and the impeller hub. Also, the higher velocity occurs near later regions. The analysis result reveals the study of flow field in the pump can provide a good guide for the axial pump designing as well as the producing practice. The velocity increases as the flow reaches to the tip blade region. Then it is decreases as the flow far away from the tip region. This is due to the high interaction flow in this area between the flow and the tip blade. Moreover, based on the numerical outcomes, it was noted that the tip blade has the high effect on the flow pattern and performance of the axial pump.
