Abstract ▼ AI-Helper

The effect of inlet and outlet blade angles on a micro regenerative pump head was examined in experiments. The pump head was little increased by changing the blade angles compared with the original pump with the inlet and outlet blade angles of 0 degree. The effect of the axial clearance between the impeller and the casing on the pump head was also examined. The head was increased largely by decreasing the axial clearance. The computation of the internal flow was performed to clarify the cause of the increase of the pump head due to the decrease of the clearance. The local flow rate in the casing decreased as the leakage flow rate through the axial clearance decreased due to the decrease of the clearance. It was found that the larger head in the smaller clearance was just caused by the smaller local flow rate in the casing. In the case of the smaller clearance, the smaller local flow rate caused the smaller circumferential velocity near the front and rear sides of the impeller. This caused the increase of the angular momentum in the casing and the head.

제안 방법

The angular momentum in the casing was investigated to clarify the relation between the leakage flow and the pressure coefficient. Figure 12 shows a control volume.
The effect of the inlet and outlet blade angles, and the axial clearance between the impeller and casing on the pressure performance of micro regenerative pump was investigated in experiments and computations. The following results were obtained.
The static pressure at the inlet, the mass flow rate at the outlet, and a non-slip condition on the wall were given as boundary conditions. Unsteady calculation was performed. The time step is 1/400 of one period of the rotation of the impeller.

이론/모형

Basic equations are the continuity equation and the Reynolds averaged Navier-Stokes equation. SST turbulence model were used.
