Mixer simulation in Comsol: Mixers are made in two types: dynamic and static. In static mixers, flow turbulence is used, and in dynamic mixers, rotating blades are used for mixing. In this project, we will simulate and analyze the fluid flow inside a mixer with the help of Comsol software. The method of mixing the selected fluid inside a dynamic mixer has been investigated. To simulate the movement of particles, Fluid Flow physics is used, and to model the movement of rotating blades, Rotating Machinery physics is used, and the geometry is assumed to be two-dimensional.
