Many theoretically and/or experimentally derived correlations have been proposed for predicting the response time of a fixed-temperature heat detector and/or a heat sensitive device of a sprinkler in a given fire scenario. These correlations have been developed on the basis of the property of the ceiling jet flow below a flat and smooth ceiling. Some previous studies have reported on the ceiling jet flow generated by a steady fire below an inclined smooth ceiling. However, the exact dependence of the ceiling jet flow on the inclination angle has not yet been clarified. Here, an experimental approach was employed to clarify the effect of inclination angle of the smooth ceiling on the decrease in temperature along the steepest run in the upward direction, horizontal distribution of temperature in the spanwise direction and the backlayering distance (velocity reversal distance) in the downward direction.
