“…Yang and Yeh 12 investigated numerically optimization of an inclined finned parallel plate channel using mixed convection heat transfer. Yaseen and Ismael 13 performed a study about the deviation caused by a baffle to improve heat transfer in a channel‐trapezoidal cavity as well as the resulting stress, it is found that the flexible baffle is shown to have less stress than the baffle. The fluid‐structure interaction and the forced convection in a partially heated channel using a constant heat flux were presented in a paper by Ismael, 14 the author declared that at Re = 250, the resulting Nu of a compliant baffled channel is increased by 94% compared with nonbaffled channel.…”

A three‐dimensional numerical laminar mixed convection analysis has been examined to investigate thermal transfer, fluid flow, and second law behaviors in an inclined channel with four heated blocks within, submitted under a constant heat flux using Al2O3–Cu water‐based hybrid nanofluid as a circulating fluid. Our main purpose is to perform a close‐to‐reality approach, which leads to results that can be applied in many experimental and industrial fields. This study focuses on the analysis of the effect of Reynolds number (100 ≤ Re ≤ 500), Richardson number (0.1 ≤ Ri ≤ 2), nanoparticles concentration (0 ≤ ϕ $\phi $ ≤ 0.05), blocks positions, and inclination of the channel (0° ≤ θ ≤ 90°) to examine the variation of Nusselt number Nu, temperature gradient entropy Sh, fluid friction entropy Sf, and the number of Bejan Be. Results show that the enhancements provided to the Nu number by elevating previous parameters reached a percentage rate of 3.2% when increasing ϕ $\phi $, 12.9% with Ri, and 8.58% with Re; however, the aligned position reveals higher values. There is also an increment in Be number when Ri and Re increase, but in this case, the not‐aligned position reveals the highest values. To predict Nu number values, correlations were developed to examine the effects of ϕ $\phi $, Ri, and Re on Nu, for both aligned and not‐aligned positions.
