Multi-Purpose Mechanical/Capillary Hybrid Pump Loop 2003-01-2388

A novel type of two-phase loop is introduced which can work in any of mechanical, capillary, or mechanical/capillary hybrid modes and would allow us to make various experiments in parallel. A key component of that loop is a three-port (liquid in, liquid out, and vapor out) capillary pump evaporator coupled with mechanical pumps. An illustration of the proposed hybrid pump loop is given with a brief description of such critical components as the above. A mathematically formulated computational analysis procedure is then presented for the preliminary design of that loop. The procedure consists of a series of theoretically derived algebraic expressions; upon which all the related components are suitably sized in diameter, thickness, length, or volume. Obtained numerical results of a parametric design study are graphically shown in the figures as a function of the baseplate temperature or the heat load.
