With the quick advancement of new technologies, particularly microfluidics, it is critical to research in this field. A subsection of this discipline, Micromixers play a crucial role in various pharmaceutical and medical areas. One of the essential functions of micromixers is to maximize the mixing of two fluids. The current research examined the effect of the curvature and velocity of the inlet fluid on the mixing quality. The simulations were carried out in two dimensions using the COMSOL software version ۵.۴. The data indicate that as the radius increases, the mixing rate decreases. Also, verifying input rates of ۵, ۱۰, and ۲۰ mm per second in radii ۱, ۲, and ۴ reduces the mixing rate as the input speed rises. It suggests that the fluid had a larger possibility of molecular diffusion at low speeds.
