概要
- 論文の詳細を見る
Boiling heat transfer experiments are performed on a Freon 113 upward flow in a uniformly heated tube, and the liquid film flow rate and the size of drops entrained in the vapor core are measured at the exit end of the heated tube. The exit film flow rate at the critical heat flux condition is near to zero in a range of low heat fluxes, but it shows a trend to increase with increasing heat flux over a certain value. An empirical equation for the arithmetical mean diameter of the entrained drops is proposed, and it has been shown that the size distribution of drops can be suitably described by a gamma distribution.
