Influence of coupling liquid on acoustic focusing in ultrasound therapy;

The fluid pressure equation is combined with vibration equation of silicon diaphragm to construct liquid-solid coupling system equations for a micropump.

In order to ensure the safety production under the condition of fully-mechanized caving in Dafoshi coal mine of Binchang mining area,we studied the mechanism of roof water inrush resulted from roof fall and simulated the mining process of the first coal mining face using the solid-liquid coupling material.

A Solid-Liquid coupling mathematical model for permeating consolidation problems under finite deformations is built up, which reflects Solid-Liquid mutual coupling.

There are broad applications for the research on vibration characteristics of fluid-filled pipeline fluid,which has very important function for the progress of basic science theories and the development of national economy,fluid-structure interaction,the research on vibration characteristics in fluid-filled pipelines are studied,research methods and their application scope are analyzed.

The research of the rotary slender beam fluid-structure interaction dynamics analysis was presented the theoretical significance and application for the structure optimized design and the optimization of the process parameters.

In view of the problem of pipeline excitation,from the simplified model of water hammer wave and the fluid-solid coupling model of water hammer wave and the influence among fluid-structure interaction,the formula of length between hydraulic parts is deduced in transient excitation of the pipeline.
