Unsteady Couette granular flows
Physics of Fluids, 1997Unsteady Couette granular flows are investigated both theoretically and by the means of the discrete element method (DEM). Theoretical formulation of the problem is based on the kinetic theory for smooth, nearly elastic particles. The resulting boundary value problem is solved numerically for two particular types of flows: (a) transient Couette flows ...

Flow volumes are extended for use in unsteady (time-dependent) flows. The resulting unsteady flow volumes are the 3 dimensional analog of streamlines. There are few examples where methods other than particle tracing have been used to visualize time varying flows.

Steady and unsteady transonic flow
16th Aerospace Sciences Meeting, 1978An investigation of the transonic flow over a circular arc airfoil was conducted to obtain basic information for turbulence modeling of shock-induced separated flows and to verify numerical computer codes which are being developed to simulate such flows. The investigation included the employment of a laser velocimeter to obtain data concerning the mean

Unsteady Flows in an Unsteady Environment
The Physics of Fluids, 1965This theoretical study treats flows behind a shock or sound wavefront propagating into an environment which is itself allowed to be undergoing some generally unsteady (i.e., nonstationary, nonuniform, and thus nonisentropic) motion. Interest is with centrally symmetric geometries. Considerations regarding self-similarity are investigated and conditions

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.

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.
