The pumping rate is a decreasing function of the curvature and aspect ratio; however, reverse pumping can occur for large curvature values.
Webb13 dec. 2024 · First, it is not justified why the flows are attached on the upper surface with a large curvature (someone may consider the Coanda effect as an answer to this question). Further, to calculate the surface pressure distribution of an airfoil, the integration along a path normal to streamlines depends on the whole velocity field. Webbcurved housing (i.e. L- and U- shaped configurations) gave higher mass flow rates compared to a straight housed pump. Many of these studies used a curved channel with …
