| Abstract: | This paper reports the experimental study of onset of subcooled boiling and point of net vapor generation in a natural circulation system with subcooled boiling. Freon-12 was used as the working medium. In the experiments the onset of subcooled boiling and the point of net vapor generation were determined by visual observation. The influence of the system pressure, inlet subcooling of the working medium and the input power to the heated section on the onset of subcooled boiling and the point of net vapor generation were investigated in the experiments. Based on the data reduction, the calculation methods of the onset of subcooled boiling and the net vapor generation in the natural circulation system have been presented respectively. |
