Sentence examples for by the ceiling jet from inspiring English sources

The conditions emulate building fires where CO is formed in the rich, turbulent, nonpremixed flame and is transported frozen to lean mixtures by the ceiling jet which is cooled by radiation and dilution.

The relation between the entrainment properties of the ceiling jet and radial distance was experimentally investigated.

The result shows that the combustion intensity, the formation of the ceiling jet and the transport velocity of the heat flow field might be enhanced by using a ship engine room with multilayer structures instead of a single cabin.

Understanding the characteristics of ceiling jet flow is important because most fire detectors and suppression devices are designed to operate within the ceiling jet; the increases in temperature and smoke concentration within the ceiling jet become trigger occupants to begin fire-fighting action or to evacuation.

Centerline velocity decay, airspeed profiles, jet penetration on the ceiling, jet impingement on the floor, airflow pattern, and airspeed of occupied zone were analyzed via experimental data and compared with literature theoretical expressions.

In this paper the interaction between the fire ceiling jet and the flow driven by jet fans is studied using CFD simulations.

The predicted transport lag time for initial formation of the smoke layer beneath the ceiling (ceiling jet) was compared for the three tests.

The entrainment coefficient characteristic by ceiling jet was also described.

The mass flow rate of a ceiling jet spreading in the radial direction was estimated based on measurement of carbon dioxide concentration.

The attached plane jet is bounded initially by the ceiling and the insulated wall after being discharged from the jet slot.

One commercial CFD tool, CFX 11.0, was used to simulate the air velocity distribution of an attached plane air jet bounded by the ceiling and an insulated wall.
