This paper explores how the temperature and velocity change in a specific direction and the rotational velocity when nanofluids flow through triangular, rectangular, and chamfer baffles. The novelty of this article is to study and investigate the thermal and fluidic parameters of the velocity gradient and heat transferred between aluminum oxide and SWCNT nanofluids on the tensile surface. This study aims to increase the heat transfer coefficient by installing blades with different shapes. The Finite Element Method is chosen to solve the main equations. This paper utilized the RSM method to optimize the velocity of nanofluid and heat transfer as it passes through the stretching sheet. The main goal of this study mentioned in the article is to explore the impact of various vane shapes installed on the outer surface of a stretched sheet. To summarize, after analyzing the flow of SWCNT and Al2O3 nanofluids on various baffles and blades, it was found that the temperature of SWCNT nanofluid around the baffles was higher compared to the temperature of Al2O3 nanofluids. According to the results from the graphs of how fast something is turning and the factors that transfer heat in the software called Design-Expert, the best improvement happened when the velocity and temperature of the small particles in the liquid were at u = 1.12, and T = 20.18 and the turning velocity was N = 137.29.
