Experimental analysis of the influence of accumulated upper hot layer on the maximum ceiling gas temperature by a modified virtual source origin concept

This paper presents an experimental investigation to explore the influence of an accumulated hot upper layer on the maximum ceiling gas temperature of buoyancy-driven thermal flow in a reduced scale tunnel model. Experimental results show that the maximum excess temperature changes small with the de...
