The flow in a diffuser is unsteady in the range of optimum pressure recovery; diffusers can therefore be a major source of noise in pipework systems. A theory is developed to predict the frequency of this noise and good agreement with experimental results, for both conical and rectangular diffusers, is demonstrated. The acoustics of the duct to which a

This study was motivated by the focal tendency of atherosclerotic plaque to appear near arterial junctions. A two-dimensional bifurcation was selected to provide preliminary information on branch flow dynamics. Superseding previous steady flow estimates in similar branches, digital solutions for two flux waves have been obtained to reveal temporal and ...

AbstractPoncin's Navier‐Stokes solution for the falling head viscometer is obtained more directly by a Laplace transform method. Approximations which facilitate numerical evaluation are derived and Grumbach's result for an infinite capillary is obtained as a limiting case.

UNSTEADY COMPRESSIBLE FLOW IN DUCTS
The Quarterly Journal of Mechanics and Applied Mathematics, 1954SUMMARY A rarefaction wave is produced in a two-dimensional channel by the impulsive retraction of a piston. In a finite section of the channel there is a slight variation in cross-section, and the effect of this variation on the rarefaction wave is considered.

On Unsteady Nonlinearized Conical Flow
Journal of the Aeronautical Sciences, 1952It is shown that the equations of unsteady, nonlinear, nonviscous, nonheat-conducting flow may be put in a conical form. The problem of a shock striking an infinite wedge is considered. An invariance relation is established, and certain properties of the reflected shock are examined.

Hydromagnetic unsteady flow due to an unsteady plate
Astrophysics and Space Science, 1978The unsteady flow near an infinite flat plate, which is oscillating harmonically in its own plane, is studied in the presence of a magnetic field subjected to suction or injection. The magnetic field is perpendicular to the plate and the flow of viscous incompressible and electrically conducting fluid is regarded as being initially at rest.

Unsteady magnetohydrodynamic flow with variable flow rate
1985The problem of unsteady magnetohydrodynamic channel flow due to an arbitrarily time-varying flow rate has been solved for a fluid of anisotropic electrical conductivity. The velocity and wall shear stress have been calculated for a given flow rate. It is found that the effect of exponential flow rate is to flatten the velocity profiles and to reduce ...

The problem of turbulence is certainly one of the well-known “unsolved” problems in mechanics. It has challenged some of the most respected scientists of our times. New physical concepts have thus been invented, and the efforts to understand the problems stimulated the development of elegant stochastic theories.
