Secondary Circulation in Fluid Flow - NASA/ADS

WebIn fluid dynamics, a secondary flow is a relatively minor flow superimposed on the primary flow, where the primary flow usually matches very closely the flow pattern predicted using simple analytical techniques and assuming the fluid is inviscid. (An inviscid fluid is a theoretical fluid having zero viscosity.). The primary flow of a fluid, particularly in the … Web26 Jun 2015 · Kicks. A kick is a well control problem in which the pressure found within the drilled rock is higher than the mud hydrostatic pressure acting on the borehole or rock face. When this occurs, the greater formation pressure has a tendency to force formation fluids into the wellbore. This forced fluid flow is called a kick. Web22 Mar 2005 · The pump midplane counter-clockwise secondary flow circulation was primarily caused by the interaction of the pressure-to-suction side jet/wake nonuniform flow (and the associated normal vorticity component) with the high radial/axial flow turning angle the flow underwent while passing through blade passage. ...

Web12 Apr 2024 · In channel bends, flow separation generates recirculating eddies on the lee side that have lower pressure than the upstream flow, and this creates bend-scale form drag that accounts for much of the drag increase. Additionally, the secondary circulation due to flow curvature in bends transports high-momentum fluid from the surface toward the bed. Websecondary flow is proportional to the lateral gradient of near-wall velocity. The near-wall secondary flow always moves from the region with lower velocity (or lower boundary …
