Experimental and numerical investigation of thermal chaotic mixing in a T-shaped microchanne

Experimental and numerical investigation of thermal chaotic mixing in a T-shaped microchanne

In this paper, thermal chaotic mixing characteristics of two miscible fluids in a T-shaped microchannel are investigated experimentally and numerically. In the experiments, fluorescent dye Acid Yellow and Rhodamine B was employed to show the mass mixing behavior and temperature field, respectively....
