Slurry mixing device with microchannels for gelcasting

摘要

We developed a slurry mixing device with microchannels. Each channel has a width of 500 μm and a height of 75μm with oblique ridges on the wall with the aim of rotating the slurry and enhancing the chaotic mixing efficiency. The effect of the oblique ridges on the slurry mixing efficiency was investigated for various ridge angles (30°, 45°, and 60°). We found that the slurry was successfully mixed by the channels with oblique ridges and that channels with a 45° ridge angle had the highest mixing efficiency.
