Abstract
There are two coefficients termed as “slip factor” and “shock loss (incidence) coefficient” that play an important role in performance and designing process of regenerative pumps. In this research, numerical simulation of regenerative pumps with incompressible flow and different dimensions of channel is conducted. A new technique is presented for accurate computation of “slip factor” and “shock loss coefficient” from numerical simulation of the pump. This technique is applicable to different sizes and models of regenerative pumps. By employing the presented technique, the influential coefficients and circulatory flow for two small regenerative pumps are examined quantitatively. Quantitative and accurate computation of shock loss coefficient and slip factor in regenerative pumps through numerical simulation is new to the literature. Finally, changes of the coefficients in a pump are examined as channel dimension changes.
