In this paper, free heat transfer (H_T) and the entropy generation (E_gen) of Alumina/H_2 O nanofluid (NF) in a square cavity (CV) are simulated owing to its application in solar collectors. For this purpose, a square CV with an angle γ is placed under a fixed magnetic field. The upper wall has a temperature of Tc and sidewalls are insulated. On the lower wall of the CV, which is also insulated, two half-pipes with a temperature of Th is mounted. In the middle of the CV, there is a partition with a conductivity coefficient. The Control volume method is employed to follow the SIMPLE algorithm for the simulation. The variable parameter included 10^3

膜对下壁有两个恒温半圆形源的腔内纳米流体传热和不可逆性的影响:适用于太阳能集热器

在本文中,由于其在太阳能集热器中的应用,模拟了方腔(CV)中氧化铝/H_2 O纳米流体(NF)的自由传热(H_T)和熵生成(E_gen)。为此,将角度为 γ 的方形 CV 置于固定磁场下。上壁的温度为 Tc,侧壁是隔热的。在同样绝缘的 CV 的下壁上,安装了两个温度为 Th 的半管。在 CV 的中间,有一个带有电导系数的分区。控制体积法用于遵循 SIMPLE 算法进行模拟。可变参数包括 10^3
