Combined evaporating meniscus-driven convection and radiation in annular microchannels for electronics cooling application

This paper presents a mathematical model for the simulation of evaporating meniscus-driven dielectric coolant flow in a channel between two parallel flat plates, one of which is heated and simulates the I.C. chip surface to be cooled, and the other is assumed to be insulated for convenience of modelling. The model comprises of the energy and momentum equations which incorporate the Young-Laplace equation for the driving force. The coolant rise length, velocity and capillary number are obtained for various coolants at different heat fluxes and channel inclinations. The data generated give the domain of feasibility of the concept and may be useful in the thermal design of electronics cooling.
