Modeling of the parallel-competitive reaction of Villermaux-Dushman in selected microreactors Using COMSOl Software
A significant part of the chemical process is the mixing and mixing process. In this research, it has been tried to simulate the mixing of the Villermaux-Dushman reaction using the COMSOL Multiphysics simulation software for two microchannels with specified square and trapezoidal dimensions to achieve the minimum output separation index. Experimental data were used for the inputs to the software. The effect of volumetric flow on the Xs, separation index, as a measure of mixing quality and the drop in microchannel pressure was investigated. The results of modeling show that for all flow rates, the T-shaped micro-channel with square cross-section with separation index close to zero (0.0067-0.0001) performs better than T-shaped micro-channel with trapezoidal cross-section. The pressure drop, both in model work and experimental work, was varied in the range of 0.01 to 0.3 bar by changing the flow rate from 1 to 18 ml/min, in discharge. The pressure, velocity, and separation index contours were compared for each microchannel. Also, the software used has shown that it has a fairly high accuracy in modeling the parallel reaction of iodide-iodate.
