Abstract
A study was conducted to develop a three-dimensional unsteady mathematical model for modeling the joint motion of liquid film and gas in the microchannel during local heating while considering evaporation generalizing the earlier models. Convective heat transfer in liquid and in gas and the temperature dependence of the liquid properties were considered for conducting the investigations. It was observed that the gas-liquid interface was deformable and the evaporated substance was an impurity in the gas phase, which insignificantly affected the thermodynamic properties. The transport processes in the liquid and gas were described by the Navier-Stokes, continuity, energy, and diffusion equations. The upper wall of the channel was considered adiabatic and impenetrable, while the thermal condition was put on the lower wall of the microchannel, which considered the possibility of setting the substrate temperature dependent on spatial variables or thermal flow.
