Theoretical relations are derived between material properties and the torque measured in transient flow experiments using the parallel‐plate and the cone‐and‐plate geometries. The formulas are similar to well‐known expressions from viscometric flow theory, except in the parallel‐plate case where the differentiation with respect to edge shear rate is ...

TRANSIENT SIMULATION OF RADIATING FLOWS
Proceeding of the 4th International Symposium on Radiative Transfer, 2004Abstract Time-dependent Navier–Stokes equations are solved in conjunction with the radiative transfer equation by coupling a previously developed direct numerical simulation-based computational fluid dynamics code to an existing radiation code, both based on the method of lines approach.

Transient Poiseuille Flow Separation
The Physics of Fluids, 1971The time varying flow through a pipe is analyzed. Separation velocity profiles obtained under the influence of periodic pressure fluctuations were evaluated. These velocity profiles are compared with relaxed and unrelaxed separation concepts. It is found that a one parameter correlation is too limited to cover all possivle separation cases.

Equations for the conservation of mass and momentum describe the transient flow in closed conduits. These equations are usually referred to as the continuity and momentum equations. Some authors call a simplified form of the latter, the equation of motion or the dynamic equation.

Transient Cavitating Pipe Flow
Journal of Hydraulic Engineering, 1983When a liquid column in a pipeline is pulled apart by the upstream velocity being less than the downstream velocity for a sufficient period of time, cavitating flow occurs over portions of the pipeline. The cavitating flow, with vapor pressure at its surface, is acted on by friction and by gravity (for sloping pipes). Analytical equations are developed

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.
