摘 要: 本文数值求解了带绝热隔板的二维矩形方腔内非对称离散热源驱动的自然对流。流线和热线作为对流传输可视化技术被应用于描述分别在不同热源强度比(Br)和不同隔板高度值时方腔内的热质传输结构。结果表明热线能直观准确地揭示复杂自然对流的客观规律。 Natural convection in the two-dimensional rectangular enclosure with asymmetric discrete heat sources and adiabatic partition was numerically investigated.The streamline and heatline as the visualize technique of convection transport were applied to depict the heat and mass transport structure.The ratios of the two thermal sources strength and the adiabatic partition's height were considered in details.The results showed that heatline can vividly reveal the nature of the complicated natural convection.
