Influence of confluence angle between inlets on the mixing performance of micro-mixer with obstacles

Abstract

Numerical studies have been carried out to analyze the effect of confluence angle between two inlets on the mixing performance and pressure drop characteristics for flow in straight micro mixer with obstacles along the channel width. The comparison has also made with micro mixer without obstacle. The mixing efficiency and pressure drop are presented in terms of the confluence angle, Reynolds number (Re), and Schmidt number (Sc). It exposes that the mixing characteristics are altered significantly by changing the confluence angle. The mixing efficiency enhances with an increase in confluence angle between inlets, and the corresponding pressure drop also increases. The mixing efficiency and pressure both are higher for the micro mixer having obstacles compare to that of micro mixer without obstacle.
