Abstract

Radiative nanomaterial thermal behavior within a permeable closed zone with elliptic hot source is simulated. Darcy law is selected for simulating permeable media in existence of magnetic forces. Contour plots for various buoyancy, Hartmann numbers and radiation parameter were illustrated. Carrier fluid is AlO-water with different shapes. Outputs prove that conduction mode augments with enhance of Ha. Nu augments with considering radiation source term.

摘要

模拟了具有椭圆形热源的可渗透封闭区域内的辐射纳米材料热行为。选择达西定律来模拟存在磁力时的可渗透介质。给出了不同浮力、哈特曼数和辐射参数的等高线图。载液是不同形状的氧化铝 - 水。结果表明,传导模式随着哈特曼数的增加而增强。考虑辐射源项时努塞尔数增加。
