Abstract It is noticed that the buoyantly convective flow of non-Newtonian fluids equipped in the closed cavities is not investigated at the large frame in comparison with the viscous fluids. This is because of the complication of computational boundaries. Therefore, the present analysis is a notable attempt to examine the non-Newtonian fluid equipped in a rhombus-shaped enclosure. The heated T-shaped fin is embedded in a flow field to report the heat transfer aspects. The no-slip condition is implemented at boundary walls of the enclosure and T-shaped fin. The rhombus cavity rooted with T-shaped fin comprises of the cold, adiabatic and heated boundary assumptions. The physical problem is controlled in terms of the differential system. For solution purpose, the finite element method is utilized. It is noticed that the stream function maximized and minimized in an equal magnitude towards Rayleigh number. It is observed that the average Nusselt number along the T-shaped fin is found an increasing function of Rayleigh number. The Casson fluid temperature along the vertical line of fin shows inciting nature for both the Casson fluid parameter and Rayleigh number.

非牛顿流体流菱形固体材料域(RSSMD)的混合网格分析

摘要 值得注意的是,与粘性流体相比,封闭腔体中的非牛顿流体的浮力对流没有在大框架下进行研究。这是因为计算边界的复杂性。因此,目前的分析是对菱形外壳中装备的非牛顿流体的显着尝试。加热的 T 形翅片嵌入流场中以报告传热方面。无滑移条件是在外壳和 T 形翅片的边界壁上实现的。以 T 形翅片为根的菱形腔由冷、绝热和热边界假设组成。物理问题是根据微分系统控制的。为了求解目的,使用了有限元方法。注意到流函数以相同的幅度最大化和最小化到瑞利数。据观察,沿 T 形鳍的平均努塞尔数是瑞利数的增函数。沿翅片垂线的卡森流体温度对卡森流体参数和瑞利数均显示出激励性质。
