State of art of different kinds of fluid flow interactions with piezo for energy harvesting considering experimental, simulations and mathematical modeling

Energy harvesting system has become one of important areas of research and develops rapidly. How to improve the performance of the piezoelectric vibration energy harvester is a key issue in engineering applications. There are many literature on piezoelectric energy harvesting. The paper places focus on summarizing these literature of mathematical modeling of piezoelectric energy harvesting, ranging from the linear to nonlinear, from early a single mechanical degree to piezoaeroelastic problems.

Qualitative Characteristics

Numerous authors have studied Energy Harvesting Shock Absorbers (EHSA) over the last decade, proposing different designs with diverse geometries, parameters, and components. This article analyzes the energy recovery potential of two types of rotational EHSA, those that use ball-screw and those based on cable transmission. This paper presents the design, manufacturing and mathematical modeling of both options as well as the estimation of the potential power recovery with both technologies. Two types of vehicles are used as references, each one with the characteristic curves of their shock absorbers. Results are presented for different vehicle speeds and road types. Finally, some qualitative characteristics of both EHSAs are detailed to be taken into consideration for their possible use in vehicle suspension.

Multiphase Fluid

This work provides information about polymer composite manufacturing by using liquid composite material molding, with particular reference to resin transfer molding process (RTM). Herein, several topics related to porous media, fluid flow, mathematical modeling, computational methods, composite manufacturing and industrial applications were presented. Simulation of resin flow into a fibrous (reinforcement) inserted in a parallelepiped mold has been performed, using the Ansys FLUENT®software, and different results of resin volumetric fraction, stream lines and pressure distribution inside the mold, and volumetric fraction always flow rate (inlet and outlet gates) of the resin, as a function of filling time, have been presented and discussed.
