..., similar to a turbine. This study focused on the effect of tip clearance size on the internal flow during windmilling operations. Therefore, detached eddy simulations were conducted at three tip clearance conditions: without clearance, design clearance, and wide clearance. Consequently, the total pressure...

... clearances are difficult to maintain during manufacturing as it calls for special manufacturing process. It is well established in experiments that both head and efficiency decrease with increase in tip clearance and are quite sensitive to rather small change in clearance. It was planned to carry out...

... turbulence flow of the double suction pump was carried out in this paper and then the distribution of axial velocity and static pressure within the tip clearance was obtained. The results indicate that the leakage flow and the secondary backflow, which occurs at some special regions, are observed obviously...
