| Outline of Final Research Achievements |
In this study, fundamental and academic elucidation on strong water cooling heat transfer of high temperature steel slabs necessary for high functioning of steel materials was promoted by advanced experimental investigation. An experimental apparatus for measuring the high-temperature surface heat transfer characteristics of water impinging jet flow was completed. Furthermore, the heat transfer measurement in the vicinity of stagnant point of water impinging jet flow was carried out. As a result, the initial assumption predicted from the heat transfer coefficient in the conventional steel cooling study greatly differs from the heat transfer characteristics of this study. For the heat transfer measurement on the high temperature solid surface, it was clarified that more than tenfold increase of heat flux is required as compared with the heat transfer block for this experiment. It is necessary to further sophisticated new research.
