In the case of fires occurred in a huge shop and a factory, which have a large floor area, a smoke layer with relatively thin thickness is formed by hanging smoke barriers which are installed in each constant area to prevent the spread of smoke layer. Some studies on ceiling jet temperature property which flows through the smoke layer with thick thickness accumulated in a compartment were presented. However few study on ceiling jet temperature which flows through the smoke layer with thin thickness formed by hanging smoke barriers. Using both the small-scale fire experimental results, which were conducted with varying heat release rate, depth of hanging smoke barrier and ceiling height with a horizontal ceiling, and the idea of Yamauchi's correlation, which can estimate temperature of ceiling jet in arbitrary radial position in the space where smoke layer with thick thickness is formed, a new correlation which can estimate the ceiling jet temperature which flows through the smoke layer with thin thickness is presented.
