Transient two‐layer thin‐film flow
International Journal for Numerical Methods in Fluids, 2011AbstractThe transient two‐layer thin‐film planar flow is investigated theoretically in this study. The interplay among inertia, viscous and surface/interfacial tension is emphasized. It is found that the film and interface profiles, as well as the flow field, are strongly influenced by the viscosity ratio, velocity and film thickness ratios at ...

Application of Transient- Multiphase-Flow Technology
Journal of Petroleum Technology, 1999Distinguished Author Series articles are general, descriptive representations that summarize the state of the art in an area of technology by describing recent developments for readers who are not specialists in the topics discussed. Written by individuals recognized as experts in the area, these articles provide key references to more definitive work ...

ABSTRACT The results of a numerical investigation of the flow of space-charge under non-steady state conditions in a parallel plane diode are described. These show how the steady state is set up from an initial state, or in the case where a virtual cathode is formed, how a quasi-steady state is established.

Numerical investigation of transient nozzle flow
Shock Waves, 2003The starting process of two-dimensional and axisymmetric nozzle flows has been investigated numerically. Special attention has been paid to the early phase of the starting process and to the appearance of a strong secondary shock wave. For both cases, shock intensities and velocities are obtained and discussed.

Transient growth in core-annular flow
2009The classical problem of the stability of Core-Annular Flow (CAF) in pipes is here reconsidered from the point of view of linear non modal analysis. An accurate Chebyshev pseudospectral code in polar coordinates has been developed in order to separately discretize the two phases of the flow.

The use of cavity reveals many problems related to the application of weapons storage mechanisms, as the opening of doors at subsonic and supersonic speeds produces high intensity noise which could damage the internal stores and surrounding cavity structures.

STRUCTURAL CHANGES IN TRANSIENT STOKES FLOW
The Quarterly Journal of Mechanics and Applied Mathematics, 1995The paper examines the unsteady Stokes flow past an axisymmetric body focussing attention on the possibility of flow separation and formation of eddies in the fluid, especially in the transition from one quasisteady flow to another. The oscillatory flows past a sphere and an oblate spheroid are determined.

In the previous chapters, we considered transient flows in the closed conduits. In this chapter, we discuss transient flows in open channels. A flow having a free surface is considered open-channel flow even though the channel may be closed at the top, e.g., a tunnel flowing partially full.

Transient Fluid Flow Through Composite Geometries
Proceedings of International Petroleum Conference and Exhibition of Mexico, 1998Abstract The equations describing the transient flow of a fluid with low compresibility through a series of connected porous media with contrasting geometries and/or properties were coupled into one single vector equation.
