Experimental study of heat transfer with a jet flow in the complex space of small steel containment

Abstract

To study the heat transfer phenomenon in the complex space of small steel containment during the jet flow, the experiments and simulation were conducted with various jet inlet temperatures, velocities, and heights. The results show the flow field and temperature field are quite different from the large containment. There is no obvious thermal stratification phenomenon in small containment during the jet flow. The temperature in the lower part of the containment which is below the jet almost uniform. The temperature filed above the jet is more complex and depends on many factors. With the jet temperature increases, the temperature field above the jet increases obviously and the lower part increases slightly. The higher jet velocity, the higher initial kinetic energy, and the flow are easy to reach the dome and form a circulation.
