Примери за unsteady

• Doctors may perceive Seniors as physically unsteady, so bumps and bruises are more easily explained away.

• He said people now are looking for something to give them peace of mind in unsteady times.

• There is one class of unsteady turbulent flows, however, that has been studied in fair detail using moderate to highly sophisticated data, reduction techniques.

• They performed an extensive set of experiments studying steady and unsteady viscous jet behaviour.

• We present a model of sedimentation in a subsiding fluvio-deltaic basin with steady sediment supply and unsteady base level.

• Exact analytical representations are obtained describing self-similar unsteady flows of multiphase immiscible fluids in the vicinity of non-circular, but constant strength, fronts.

• As another example, consider transport in the vicinity of a single unsteady vortex ring.

• The interior unsteady flow shows source-like behaviour at the corners.

• The flow within the duct is taken to consist of a steady mean flow with unsteady acoustic perturbations.

• The present analyses advance the previous quasi-steady models by being formulated for a fully unsteady flow system, with no time-derivative terms being neglected.

• This approximation, according to which the unsteady terms in the equations of motion of the flow can be neglected, is adopted here.

• The driving mechanism results from unsteady coupling between flame structure and acoustic waves through temperature fluctuations.

• These large-scale instabilities give rise to unsteady flow throughout the inner layer.

• Whenever the jet impinged on the cavity wall the latter became rough, unsteady and opaque as in the bottom lefthand corner of figure 1 (c).

• The governing equations in the water are therefore those of unsteady potential flow, while those in the air are of lubrication.

• The unsteady expansion of an ideal gas into a vacuum is studied in one-dimensional planar and spherical geometries.

• Economic conditions were unsteady, with several depressions and recoveries, while business organizations were transformed into hierarchical and inclusive corporate structures.
