Theoretical and experimental research on influencing factors and rules of flow-induced rudder system vibration

Zhongguo Jianchuan Yanjiu, 2017
Flow-induced rudder system vibration has a great influence on the stealthiness of underwater vehicles. In order to study the vibration characteristics of rudder systems, a mathematical model of a binary linear flutter rudder system is built according to ...

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Numerical simulation of the airflow–rivulet interaction associated with the rain-wind induced vibration phenomenon

, 2011
Rain-wind induced vibration is an aeroelastic phenomenon that occurs on the inclined cables of cable-stayed bridges. The vibrations are believed to be caused by a complicated nonlinear interaction between rivulets of rain water that run down the cables ...

Flow Induced Vibrations in Engineering Systems and the Control of Flow Induced Vibrations. Chaotic Vibration in Poppet Valve Circuit.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995
In the previous paper we pointed out that chaotic vibrations can occur in poppet valve circuits due to nonlinearities. The chaotic motions in the poppet valve circuits include (a) period-doubling-type chaos, (b) Lorenz-type chaos and (c) intermittent-type chaos. In this paper, period-doubling-type chaos has been investigated in detail.

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

Vortex-induced vibrations of a long flexible cylinder in shear flow [PDF]

, 2010
We investigate the in-line and cross-flow vortex-induced vibrations of a long cylindrical tensioned beam, with length to diameter ratio L/D = 200, placed within a linearly sheared oncoming flow, using three-dimensional direct numerical simulation.

Advances in Micromanipulation Actuated by Vibration-Induced Acoustic Waves and Streaming Flow

Applied Sciences, 2020
The use of vibration and acoustic characteristics for micromanipulation has been prevalent in recent years. Due to high biocompatibility, non-contact operation, and relatively low cost, the micromanipulation actuated by the vibration-induced acoustic ...
