NEUTRON RADIOGRAPHY STUDY OF PULSED BOILING IN A WATER-FILLED HEAT PIPE.
Author(s) : BALASKO M., KONCZOL S., SVAB E.
Type of article: Article, IJR article
Summary
THE BOILING AND CONDENSATION PROCESSES IN A WATER-FILLED INDUSTRIAL HEAT PIPE HAVE BEEN INVESTIGATED BY DYNAMIC NEUTRON RADIOGRAPHY. PULSED BOILING WAS VISUALIZED AND ANALYZED UP TO A CHARACTERISTIC TEMPERATURE DEPENDING ON THE FILLING QUANTITY. THREE TYPICAL REGIONS WERE DISTINGUISHED: THAT CONSTANTLY FILLED BY THE LIQUID ; A PERIODICALLY WETTED ZONE ; AND A REGION CONSTANTLY FILLED BY THE VAPOUR. PULSATION IS NOT STRICTLY PERIODIC AND ITS MEAN AMPLITUDE AND FREQUENCY WERE DETERMINED. IT IS CONCLUDED THAT ANY MODELS BASED ON THE EQUILIBRIUM STATE ARE INCORRECT.
