Abstract

The microchannels play a crucial role in various lab-on-a-chip device. The performance of any microchannel is governed by the mixing characteristics and the pressure drop. This paper focusses on the comparative mixing performance analysis of serpentine microchannels with straight and curved bends. COMSOL Multiphysics 5 was used for performing the computational fluid dynamics (CFD) simulations. The aspect ratio (ratio of channel width to height) was varied as 0.75, 1, and 1.25. The inlet velocities at the two inlets were varied as 0.5, 0.75, and 1 mm/s. The microchannel width and height were 400 μm (for aspect ratio 1). The pressure variation (drop) and mixing within straight and curved serpentine microchannel is analyzed. The effect of inlet velocity on mixing length and pressure drop is studied. The influence of the aspect ratio on pressure drop is also investigated. It was noted that the pressure drop is enhanced with an increase in aspect ratio from 0.75 to 1.25
