The study on sound radiation of semi-submerged cylindrical with antisymmetric velocity distribution
نویسنده
چکیده
The vibro-acoustic characteristics of cylindrical shell are widely studied because of its strong engineering application background, especially when the shell is immersed in infinite fluid field or partially immersed. In the present paper, the method for analyzing sound radiation of semi-submerged finite cylindrical shell with antisymmetric velocity distribution is first proposed. The orthogonality of trigonometric function and sound field distribution characteristic of dipole are utilized to establish the formulas. Sound radiation diagram of representative velocity distribution is depicted. Numerical calculations show that BEM Sysnoise is an effective tool to deal with the sound radiation of semi-submerged cylindrical shell.

In this paper, submerged vanes were placed at the upstream area of a bridge pier located at the 90 degree angle. Then, using the laboratory equipment, a study of flow pattern was conducted throughout the bend, specifically around the pier and submerged vanes. ADV velocimeter was incorporated in order to help measure 3D velocity components. Submerged vanes were installed at distances of 40 and 6...
متن کاملNumerical Simulation of Flow Pattern around the Bridge Pier with Submerged Vanes
Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In the other hand, laboratory circumstances force many considered effective factors to be skipped in the scour phenomenon. In this situation, the...
متن کاملConstriction Scour In Pressurized Flow Condition (RESEARCH NOTE)
When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
