Effect of Uneven Microwave Heating of the Liquid–Liquid System on the Intensity of a Chemical Process in a Microreactor

In this paper, we study the effect of microwave heating of liquid reagents in a closed-type beam chamber on the intensity of a chemical process in a microreactor. The heating of the reagents, which is uneven along the length of the microreactor, is shown to stimulate the development of thermocapillary convection and significantly intensifies the chemical process. The maximal velocities of thermocapillary motion developed at the interphase boundary of contacting liquids depending on the specific power of internal heat sources and the longitudinal temperature gradient is numerically estimated.
