A SIMULATION OF EVAPORATING MENISCUS-DRIVEN FLOW FOR APPLICATION TO ELECTRONICS COOLING DESIGN

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