AbstractVarious wall surface emissivities are used to examine the radiative effects on the vertical air temperature profile and gravity current in a full-scale model of a room ventilated by displacement. The vertical temperature stratification is a combined effect of convection, conduction and radiation. The radiative effects are to heat the floor surface and alter the flow rate in the thermal plumes, which weakens the gravity current and lowers the stratification level. The intermittance at the upper edge of the gravity current is illustrated by studying its turbelent structure. The data gathered in this work are suitable for validating flow and radiation models. © 1993.
