Research Institution

The use of the heat of vaporization of the coolant can significantly reduce the required flow rate, and this reduction flows down throughout the thermal management system. Two-phase systems, however, are subject to buoyancy effects which can make them vulnerable to high-g maneuvers of military aircraft. Two-phase microchannel coolers can be designed such that surface tension effects dominate buoyancy forces, even in high g environments, desensitizing the thermal and flow performance to aircraft maneuvers. In the proposed effort, a two-phase microchannel cooling system with large surface tension forces will be designed, fabricated and tested to demonstrate operation. The result will be a compact, survivable cooling system with a significant reduction in flow rate compared to a single-phase water-cooled microchannel systems. Approved for Public Release 14-MDA-8047 (14 Nov 14)
