  dimensional unsteady flow

The theory of a lifting surface is used to construct a model of three-dimensional unsteady flow past a pair of flapping wings in the regime of normal hovering flight.

The problem of two-dimensional unsteady flow of a viscous incompressible fluid in a sector-like domain is considered.

In this paper, we propose a numerical method of calculating a three-dimensional unsteady flow past a thin wing in the presence of flow suction on the wing surface through a point hole or a narrow slot.

In the non-inertial coordinates attached to the model wing, the two-dimensional unsteady flow field triggered by the motion of the model wing, similar to the flapping of the insect wings, was numerically simulated.

In this paper, a study of nonhomentropic, spherical, cylindrical and one-dimensional unsteady flow of a perfectly conducting gas has been made by taking Lagrange's equations of motion.

A method is presented enabling the computation of local scouring downstream of stilling basin. The simultaneous equations consist of motion and continuity, equations for flow equation for bed-load transport (Einstein equation) and continuity equation for the bed material. In computation, the method of characteristics considering large scale vortex is used. Experiments with gravel particles (as bed-load) are selected to calibrate the mathematical model. Verification analysis shows that this model gives good approximation...

From the viewpoint of numerical computation, various forms of 1-D unsteady open channel flow equations and conservativity of their differences schemes are analysed. Based on the discussion, the authors summarize the approaches and principles for constructing conservative difference schemes for the equations, and propose practical techniques such that conservation can be achieved exactly or approximatley.

In this paper, a 1-D unsteady flow model and a quasi 2-D flow model for simulating flood flow for storage and detention basins are developed. Flow exchanges between a river reach and adjacent storage cells, discharge exchanges among connected storage cells in an inundated plain, and the compatibility conditions representing flow links between channels and a flood regulation region are all described in detail. A case study is given.
