The competition between inertia and viscosity - Reynolds

WebThe behaviour of pipe flow is governed mainly by the effects of viscosityand gravity relative to the inertialforces of the flow. Depending on the effect of viscosity relative to inertia, as represented by the Reynolds number, the flow can be either laminaror turbulent. WebThe Euler Number is a dimensionless value used for analyzing fluid flow dynamics problems where the pressure difference between two points is important. The Euler Number can be interpreted as a measure of the ratio of the pressure forces to the inertial forces. Note! - a perfect frictionless flow corresponds to that the Euler number equals 1. firehouse patio furniture charlotteWeb2 feb. 2011 · The fundamental concept of the boundary layer was suggested by L.
