STUDY OF ADVANCED TECHNIQUES FOR COOLING VERY HIGH POWER MICROWAVE TUBES (VORTEX FLOW),

Abstract

Measurements of pressure drop in test sections with twisted tape have been performed. From the accumulated data, friction factors which can be compared with those of straight tubing can be obtained. Burnout measurements have been made and fluxes of 8500 watts per sq cm have been reached with the twisted in the test tubing. Corrections for wall temperature measurements have been prepared and will be used in making heat transfer measurements. (Author)
