摘要:
为了研究内置高温体倾斜多孔腔体中流体流动与传热机理,本文采用格子Boltzmann方法从介观尺度对其多孔腔体内自然对流现象进行了模拟研究,讨论了孔隙度ε(0.4,0.7,1.0)、Da数(10-4,10-2)、Ra数(105~107)及倾角θ(0°~90°)等参数对其对流传热的影响。模拟结果表明:等温线会随着腔体倾斜向底部偏移;Da=10-4时,流线呈现对称分布特性,Da数增大时,多孔方腔右侧流线会绕过高温方块经过左边区域,流线分布发生偏移。热壁面上平均Nusselt数Nuave随倾角增大呈现特定变化规律,增大孔隙度ε、Da数、Ra数时,均可以增强流体与热壁面之间的自然对流传热能力。
