The experiment of critical heat flux was conducted in a tube of inner diameter of 7.95 mm and heating length of 0.8 m with water flowing upward, covering the ranges of pressure of 8.6 – 20.9 MPa, mass flux of 447 – 1179 kg/m2s, outlet subcooling of 1 – 96 K and critical heat flux of 0.69 – 3.68 MW/m2. The CHF characteristics and parametric trends are studied, and the experimental results are compared with the predictions of 96 CHF Look-up Table.
