Abstract Heat and fluid flow trajectories are visualized during natural convection subjected to linear heating of the inclined walls involving two representative inclination angles ( and ) for different configurations (configurations 1 − 3) of the porous isosceles triangles. Heat transport to the core and cold section of inclined walls due to linear heating is studied using heatlines via tuning various dimensionless parameters Prm , Dam at fixed Ram . Local heat transfer rates are found by evaluating Nu at the inclined walls. Overall, configurations 2 and 3 are recommended based on larger magnitudes of local heat transfer rates at middle regime of the walls, irrespective of and Prm at

在斜壁处线性加热的多孔三角形结构内自然对流过程中的流动和热图分析

摘要 在自然对流过程中，通过倾斜壁的线性加热，热和流体流动轨迹被可视化，涉及多孔等腰三角形的不同配置（配置 1 - 3）的两个代表性倾角 ( 和 )。使用热线通过调整固定 Ram 的各种无量纲参数 Prm、Dam 来研究由于线性加热导致的倾斜壁的核心和冷截面的热传输。通过评估倾斜壁处的 Nu 可以找到局部传热率。总体而言，建议配置 2 和 3 基于壁中间区域较大的局部传热率，而不管 和 Prm 在
