Researches of the of Gas Expiring From the Vortex Jet Gripping Device on the Flat Barrier

The interaction of the twisted stream of gas expiring from the vortex jet gripping device on a plane barrier is considered. The developed mathematical model allows defining a pattern of a current of a flow in the device camera, and also in a zone of contact with the retained object. Rarefaction in the field of capture and influence of different parameters on its value is defined. Value of forces of suction of a stream of compressed air allowing to retain a plane disk is received

Interaction of a Second-Order Solitary Wave With a Vertical Permeable Plane Breakwater

The purpose of this paper is to develop mathematical models to investigate the interaction between long non-linear water waves and dissipative/absorbing coastal structures. The diffraction of a plane second-order solitary wave at a vertical permeable plane barrier standing in front of an impermeable wall, with calculation of the second-order wave loading is investigated. An incident plane second-order solitary wave is the Laitone solution of Boussinesq equations. The analytical solution is obtained by means of a small parameter development and Fourier transformation techniques. Computational results were performed using the software MATHEMATICA version 4.0.1.0.

A plane vertical submerged barrier in surface water waves

By a simple application of Green's integral theorem, amplitude of the radiated waves at infinity due to a line source in the presence of a fixed vertical plane barrier completely submerged in deep water is obtained.
