폐열에너지로 구동되는 자성나노유체-버블 2상유동 사이클 나노발전 시스템

다국어 초록 (Multilingual Abstract)

As a part of energy conversion technology, we proposed a cycle nanogenerator to produce electric energy through magnetic nanofluid (MNF) flow using waste heat energy from the industry. In the proposed nanogenerator, a heat source causes self-circulation of working fluid by thermosiphon method, and two-phase flow of MNF-bubbles resulting in density difference in the gas-liquid phase. For this reason, the spatial discretization of the magnetic field occurs under an external magnetic field and the induced electromotive force is generated in a solenoid coil by Faraday"s law. The power generation test was carried out using magnetic nanofluid containing the iron oxide (Fe₃O₄) nanoparticles were dispersed in a volume ratio of 2% in the distilled water as the base fluid. The effective voltage was generated at the generating part, which was composed of permanent magnet and solenoid coil, by the two-phase flow of MNF-bubbles from 300W heat source.
