Ship manoeuvering response equation in confused wind was derived,and by means of the theory of linear system in stochastic processes,the problem of keeping course by rud-der force when ship sailing in confused wind was dealt with.

The instantaneous vortex structure of the leading-edge vortices on a delta wing in unsteady free stream is investigated via particle image velocimetry in unsteady wind tunnel of NUAA.

A pitching test set-up, used in the unsteady wind tunnel at Nanjing University of Aeronautics & Astronautics, is developed to study the effect of rapid changes on both the free stream velocity and the angle of attack.

In this paper, the effects of unsteady free stream on aerodynamics of an aircraft model are studied in the unsteady wind tunnel of NUAA.

A new dynamic overset unstructured grids method is developed to simulate the unsteady flow field a-round helicopter.

Having worked out a lot of technique problems, this paper reports quasi-3D LDV measurements of unsteady flow field in a rim sealing of a turbine stage.

The numerical simulation of the unsteady flow field around an oscillating airfoil is difficult because of the complexity of turbulence models and numerical methods.

The wake flow of stator vanes and the unsteady flow in the passage of rotor blades were solved by using oscillating fluid mechanics theory and parametric polynomial method.

The three-dimensional unsteady flow field in a centrifugal fan is numerically simulated,where Navier-Stockes equations are adopted and RNG k-epsilon turbulence model is chosen.

The unsteady flows in a agitator are calculated numerically, and compared with the author′s experimental data.

Implicit finite volume TVD schemes improved by the dual-time stepping method are applied to numerically simulate unsteady flowfield over high-speed spinning SOCBT projectile with attack angle.
