The Nukiyama curve

Shortly after the late Professor Shiro Nukiyama was notified that he was the recipient of the 1968 Max Jakob Award, a collection of his research papers was reprinted in a bound volume and published. The preface for this volume was written by Professor Yasushi Tanasawa who was Professor Nukiyama's co-worker at Tohoku University. The preface of this paper carries an interesting account of how this historic experiment was conducted. It also describes how the investigator himself came to learn, many years later, the extent of attention that his experiment had won abroad. It was learned, however, a considerable time after a meeting, that an extensive study on boiling heat transfer was being conducted in the USA because the cooling performance of a boiling water type nuclear reactor was restricted at the point of maximum boiling rate, but that a complete solution had not been obtained. On reflection, some experiments on the point of maximum boiling rate from 1929 to 1933 were made
