A Study of Natural Circulation Cooling Using a Flow Visualization Rig

Abstract

A flow visualization rig has been built at Monserco Ltd. to provide visual insight into the thermalhydraulic phenomena which occur during single and two-phase thermosyphoning in a figure-of-eight heat transport loop. The sensitivity of natural circulation cooling to the


number of heated channels, feeder geometry, channel power and header size was examined to provide design assist information for scaling a high-pressure rig.
