Numerical Analysis of Mixing Performance in Microchannel with Different Ratio of Outlet to Inlet Width
Rapid mixing is one of the prerequisites for many chemical and biological applications. Fixing the proper ratio of dimensions of the geometry is important to design an object for its performance. In this study, numerical investigations have been carried out to analyze the mixing efficiency and pressure drop characteristics for the flow through micro channel having different outlet width to inlet width ratio (σ) for different Reynolds number (Re) in the range 0.2 ≤ Re ≤ 1 and Schmidt number (Sc) in the range 400 ≤ Sc ≤ 2000 with an objective to find the optimum geometry for mixing performance. Further, the effects of obstruction along the channel wall are also assessed for all the considered outlet width to inlet width ratio. With decreasing the considered σ, mixing efficiency enhances and pressure drop also increases.
