Flow and Pressure Head at the Inlet of Narrow Passages, Without Upstream Free SurfaceSource: Journal of Tribology:;1982:;volume( 104 ):;issue: 002::page 196Author:N. Tipei

Abstract: A model of the flow at the inlet of narrow passages, based on the theory of potential flows, is presented. No free surface is supposed to exist. A boundary layer is carried by a moving boundary; the impact of the fluid with the frontal surface of the other body, at rest, generates various flow patterns, as well as a pressure head at the entrance of the gap. A complete theory is presented, then a simplified model is shown, and flow mappings are obtained. The pressure head is calculated and shows an important dependence on the pressure gradient at the inlet of the passage.
