Cantilever-based micro thrust measurement and pressure field distribution of biomimetic robot fish actuated by macro fiber composites (MFCs) actuators

Based on the principle and method of computational fluid dynamics (CFD), using the software, FLUENT, the inner water flow field in the cross-section geometric model of a triangle-arranged tubular heat exchanger was simulated and the flow details were studied roundly. This article analyzed the temperature field distribution, pressure field distribution and pointed out the main factors that affected the effect of the heat transfer. The results of this paper provided a good base and reference for the further research on the optimum design.

Acoustic Environment

In order to study the acoustic environment of a ship sonar platform, near-field acoustic characteristic of a compound structure with plates & a cylindrical shell (CSPCS) subjected to sound excitation is researched based on numerical simulation. Influence of frequency and sound incident angle on acoustic environment of CSPCS are studied. Study shows that the sound pressure field distribution of CSPCS is complicated. Sound pressure would be strengthened and weakened in different locations when sound pressure uniformly incident into CSPCS. Result shows that the sound pressure distribution is highly dependent on frequency and incident angle. Sound pressure field is more evenly distributed when sound wave frequency is low. Study also shows that the incident angle has considerable influence on the sound field distribution of strengthened and weakened area.
