Abstract: A laminar boundary-layer model is proposed to account for viscous losses during the transient turbulent flow of a liquid in a tube. In this model, inviscid slug flow is assumed for the core ...

Abstract: A single boundary layer model to account for transient viscous effects is applied to small amplitude sinusoidally disturbed turbulent flow in a tube. The viscous dissipation is calculated using ...

Abstract: An experimental investigation was conducted to determine the void fraction and pressure drop occurring in a forced-convection water electrolysis cell. It was concluded that the slip ratio is ...

Abstract: It is generally assumed that orifices and valves follow closely their steady-state characteristics during transient operation. However, this assumption of quasisteady behavior may lead to errors ...

Abstract: The transfer of energy and irreversible energy losses at junctions may dominate flow distribution in pipe networks comprised of connected large‐diameter pipes of short lengths. Neglecting the junction effects when calculating ...

Abstract: A practical technique was developed for in vivo determinations of the mechanical properties of canine left ventricle. A “quick stretch” was accomplished by rapid injection of isotonic saline ...
