WebDec 7, 2024 · Unsteady gravity current, usually released suddenly with a finite volume, is a classical type of intermittent buoyancy-driven flow [6, 7, 19, 30, 34, 36, 45, 65].It is a common physical phenomenon that the dense fluid diffused from a localized source, propagates over a horizontal/inclined boundary, displacing the less dense ambient water, … WebJun 4, 1998 · The axisymmetric flow of a very viscous fluid toward a central orifice is studied. In a recent paper, a self‐similar solution for this problem has been found. The self‐similarity is of the second kind and hence the flow remembers its initial condition only through a nondimensional constant which characterizes it.
