摘要
The motion process of a steam film on the surface of a zirconium alloy rod in cooling water was studied by numerical simulation. The effects of initial temperature of the zirconium alloy rod and cooling water temperature on the motion process and velocity of steam film were analyzed. When the cooling water is 100 degrees C and the initial temperature of the zirconium alloy rod is 650, 800, and 880 degrees C, the motion of the steam film on the surface of the zirconium alloy rod is analyzed and compared. It shows that the motion rate of the steam film is faster with the increase of initial temperature. At high water temperatures, a large number of bubbles form in the liquid surrounding the zirconium alloy rod, but at lower water temperatures, there are fewer bubbles in the liquid surrounding it.
