Abstract:

This final report describes the progress to date on six individual projects. The Effect of Working Fluid Inventory on Performance of Revolving Helically-Grooved Heat Pipes is related to an experimental analysis of working fluid inventory and its effects on the capillary limit of grooved heat pipes. Fully-Developed Laminar Flow in Trapezoidal Grooves with Shear Stress at the Liquid-Vapor Interface concerns the effects of geometry and interfacial shear stress on the pressure drop in trapezoidal grooves. Fully-Developed Laminar Flow in Sinusoidal Grooves is similar to the above, except that the sinusoidal grooves typically seen in micro-etching are examined. Micro Capillary Pumped Loop Testing deals with the design, manufacture and calibration of an experimental facility for testing capillary pumped loops embedded in silicon wafers. Design and Testing of a Thermodynamic Filling Station for Miniature Heat Pipes concerns a novel filling procedure for miniature heat pipes. Acceleration Testing of Three Raytheon Heat Pipes using the AFRLPRPS Centrifuge Table deals with the performance of heat pipes under various acceleration conditions, which were imposed by the centrifuge table located in Bldg. 71-B H-Bay in Area B of Wright-Patterson AFB.
