ABSTRACT:
An inventory control device for a pitot pump used in a two-phase flow system, such as a closed-cycle Rankine system or a two-phase cooling loop for space vehicles. In these systems, there is a change of phase between liquid and vapor, dependent upon a change of power level or thermal transport rate. With these systems being used in devices that are subject to significant attitude change or acceleration forces or zero gravity conditions, the inventory control device is gravity insensitive and utilizes a second tube mounted in the pitot pump which is connected to an external accumulator. A pressure relation is established whereby the second tube will maintain a constant level of liquid within the rotating drum of the pitot pump.
