Effects of pool size and spacing on burning rate and flame height of two square heptane pool fires

Abstract

Highlights Experimental study on burning of two heptane pools in free space was conducted. Square pool side length and spacing were changed. Both the fuel burning rate and flame height changed non-monotonically with spacing. A correlation for predicting the flame height of two pool fires was developed. The burning rate was qualified based on the energy balance of fuel surface.

Investigation of the thermal behavior effect of the surrounding material environment on the swirling flame structure

“…Thus, this supply can be done asymmetrically under the effect of the particular position of the secondary sources. If the latter are also fires, the flame‐flame interaction can be controlled by the heat release rate from the secondary fire sources 18‐25 . When the fire sources are placed sufficiently close or side by side, the flames can merge and thus behave as a single large fire 19‐24 .…”
