A series of fire tests was conducted in a 10.0 m ( L ) × 0.75 m ( W ) × 0.45 m ( H ) model tunnel with a rectangular cross section, and detailed measurements were taken of the temperature and velocity within a quasi-steady state fire-driven ceiling

In this study, we conducted detailed measurements of the temperature distribution within a steady fire-driven ceiling jet, formed in a tunnel with a rectangular cross-section. We then compared the measured temperature distributions with those for an

Motevalli and Marks and Cooper have represented temperature and velocity distributions at a given radial distance within a ceiling jet that flows under a flat, unconfined ceiling by applying either an exponential function or a trigonometric function,

It is important to understand velocity and temperature distributions within a ceiling jet, because fire detectors operate within this region. Many researchers have worked positively to clarify ceiling jet properties by means of experimental and theor

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 bee

Numerical Simulation by CFD was carried out to understand the hot current behavior in a tunnel with longitudinal ventilation. It becomes clear that fire source modeling is very important because the hot current behavior is strongly affected by the fi
