Abstract: This paper presents a numerical and experimental study of transient laminar countercurrent flow in which the pressure gradient is time-dependent. An explicit finite-difference scheme is used to ...

Abstract: Paper deals with elastic waves which may be generated in quiescent fluid by displacement of the surrounding flow boundary. In particular, the piston problem of induced laminar motion in waveguides ...

Abstract: This paper deals with elastic waves which may be generated in a fluid by the sudden movement of a flow boundary. In particular, an analysis of the classical piston, or signalling problem is ...

Abstract: It has long been known that superlaminar flow occurs in lubrication fluid films above a critical speed. The consequence of the transition from laminar to superlaminar flow is an increase in ...

Abstract: The paper presents a unified approach to the solution of laminar pipe-flow transients in which the forcing function may depend on the motion itself. The key to the solution procedure is a ...

Abstract: Conduit cross sections of nonelementary shape are the rule in biological fluid systems. Because of mathematical and experimental difficulties, however, relatively little is known about the dynamics of flow in these vessels, ...
