“…While it is extremely difficult to make accurate measurements, the inclination of the FLOW3D (figure 5a) produced plume -at approximately 70" to the horizontal -appears to be less pronounced than the 45" suggested by the PHOENICS (figure 5b) results. The PHOENICS result appears to agree more closely with the observations of Quintiere et al [16] in an earlier series of experiments. Using an identical experimental setup, they observed the flame angle for this case to lie between 33" and 43".…”

This paper describes the application of two fire field models to the description of fire induced flows in domestic sized rooms. A systematic and critical comparison is made of two commonly used CFD codes for fire modelling, PHOENICS and FLOW3D. Comparisons are based on upper-layer room temperatures, mass fluxes in and out of the fire compartment and door-way vertical and horizontal temperature and velocity profiles. Given identical meshes, both models agree reasonably well with the observed trends. A close examination of the horizontal door-way velocity profiles highlights the need for careful modelling and experimental practices.

“…Thomas [4] and Hamada [5] showed the correlation between the tilt angle of a flame and its burning rates using a solid fuel set on the ground in an open space condition. Raj [6] correlated flame angle for LGN pool fire when the flame was blown, and Quintiere [7] reported also the flame angle affected with a door jet. These previous works [l-71 dealt with the flame inclination in the case of a fire source set on the ground or on floor.…”

A reduced-scale experimental study was carried out to collect a knowledge of the effect of external side wind on the flow behavior of a flamelplume which is ejected from an opening of a fire compartment. The external side wind was given to the flamelplume at the various speeds of 0.06misec to 1.88misec. Upward velocities and temperatures of the flamelplume were measured systematically along the wall for vertical and horizontal directions and which gave the trajectory (trace of main flow axis). Decreasing temperature and upward velocity for vertical direction showed similar behavior to those obtained in the flow from a line fire source. The slope of the trajectory inclined by side wind and of which slope was estimated based on the experimental data. A simplified model on the trajectory slope (or flame inclination slope) can be described by the coupled function of dimensionless heat release rate, Froude number and the aspect ratio of the opening base on the balance of buoyancy and inertia force of side wind as well as the aspect ratio of the opening and heat release rate.

“…Quintiere [11] has recently explored some quantitative effects of nonsymmetric air supply on gas flows and entrainment. Results for x can, in principle, be compared to bench-scale measurements [20] if losses are small or are similar in both cases.…”
