Experimental study of heat transfer through cover gas in LMFBR

Experimental investigation were performed on the combined radiation and natural convection heat transfer through the cover gas space over the sodium pool. The amount of heat transmitted from the hot sodium to the cold wall through the gas space folled with sodium mist was measured. The thermophysical properties such as the thermal emissivities of liquid sodiim and mist-deposited stainless steel and the radiative characteristics of mist-filled space were also measureed using especially devised anparatus. The amount of heat transmitted through the space, measured by experiments, was compared with the analytical results based on the measureed thermophysical properties. The agreement was comparatively good between the experiment and analysis.
