Technological and Scientific Review of Nucleate Pool Boiling Experiment Conducted by TR-lA No. 5 and Comments for the Improvement of Further Investigation (1st Report)

Abstract

To obtain the detailed heat transfer data and the data concerning directly to the heat transfer mechanisms, i.e. the liquid film thickness underneath attached bubbles, a structure of transparent heating surface was investigated for the TR-IA No. 5 rocket experiment conduct­ed in September, 1996. The sequence of various combinations of system pressure and supplied heat flux level was developed to ensure the boiling initiation, the establishment of ex­perimental conditions for succeeding subdivided phases and the removal of accumulated bub­bles. Based on the experimental results and analysis, the summary and comments about the experimental hardware, the sequence of system parameters varied, the structure of coalesced bubble are presented as the first report for the purpose of the improvement of further studies in the same research field.
