Numerical simulation of heat and mass transfer processes in microchannels using CFD-package $\sigma$Flow

This article is dedicated to numerical modeling of heat and mass transfer processes in microchannels. Microchannels are channels, that characteristic diameter is about 100 $\mu$m. Interest to the study of processes in them is growing every year, due to the rapid development of microfluid technique. The study was conducted using the software package $\sigma$Flow. Isothermal and nonisothermal flows in microchannels of various configurations were considered. The obtained results were compared with available experimental and analytical data. In general for all problems a good agreement was obtained.
