Flow analysis of water with aluminum oxide nanoparticles in a 90° bend pipe with injection using computational fluid dynamics

In several heat exchangers, the shape of the pipes is bent. Flow behavior in a curved tube is much more complex than straight pipes. Also, Nano-fluids are utilized in many industrial applications for increase thermal efficiency. Therefore, the aim of this study is investigation of the effect of i...
