Abstract:
A recent study has developed an electromagnetic energy harvester that can harvest energy from flow-induced vibrations in real-time by using a magnet in translation within a coil. As part of this system, a flow channel is connected to a flow source by a flexible diaphragm, and a square cylinder acts as a bluff body, oscillating the diaphragm with an attached permanent magnet surrounded by a coil, there-by generating electrical energy. Using electromagnetic induction and fluid flow, it converts flow en-ergy into electrical energy. The influences of the Reynolds number (Re = ۳۰۰۰, ۴۰۰۰, and ۵۰۰۰) and the position of square cylinder (X*=X/D) on the dynamic characteristics are considered. In light of the results, it becomes clear that the Reynolds number and incidence angle play an influential role in the amount of energy harvested from the interaction between fluid and a square cylinder. The higher Reynold number prescribes, the higher voltage can be obtained. Furthermore, an experiment has shown that an output voltage of ۰.۰۳ V can be generated when a diamond configuration is employed. Having employed three typical incidence angles of α = ۰○, ۲۲.۵○, and ۴۵○, overly, α = ۴۵○ is the most suitable arrangement for the conversion of power.
