Abstract In this article, Lorentz forces impact on Nano enhanced PCM heat transfer during discharging process is simulated in a storage porous unit by means of computational method namely FEM. Lorentz forces and nanoparticles are utilized to accelerate this unsteady phenomenon. Impacts of volume fraction of NEPCM, Hartmann and Rayleigh numbers on discharging process were illustrated. Results reveal that employing Lorentz forces can augment the discharging rate. Discharging time decreases by dispersing nanoparticles.

多孔储能系统凝固过程中洛伦兹力对NEPCM传热的影响

摘要 本文采用有限元法(FEM)模拟了蓄能多孔单元中放电过程中洛伦兹力对纳米增强PCM传热的影响。洛伦兹力和纳米粒子被用来加速这种不稳定的现象。说明了NEPCM体积分数、哈特曼数和瑞利数对放电过程的影响。结果表明，采用洛伦兹力可以提高放电率。通过分散纳米粒子减少放电时间。
