The purpose of this work was to investigate maximum disperse phase flux required for production of monodisperse drops in a straight-through microchannel (MC) array device. The experiments have been carried out using single-crystal silicon MC plate consisting of about 23,000 asymmetric MCs fabricated by photolithography and deep reactive ion etching (DRIE). Each MC consisted of a rectangular 50×10 μm slot and a circular 10 μm-diameter hole in the middle of each slot. A depth of the hole was 70 μm and the slot depth was 30 μm. The dispersed phase was soybean oil, MCT (middle-chain fatty acid triglyceride) oil and n-tetradecane with a viscosity at 293 K of 50, 20, and 2.7 mPa·s, respectively. The continuous phase was 2 wt% Tween 20 or SDS. (Continues...).
