Numerical Investigation of Wind Effects on the Flame Shape of Sarkhoon and Qeshm's Refinery Flares

Due to considerable height of the flaring flames, wind speed has siginificant effects on its flame shape and cause consequent damages. In this paper, the effects of wind speed on the flame shape and the temperature distribution of the flare wall are investigated using three-dimensional numerical simulation of turbulent combustion. Results show that at wind speeds higher than 5m/s, the flame lies over the flare wall causing its temperature to increase. Moreover, as the wind speed changes, the position of the maximum temperature point on the flare wall also changes, causing the material to experience fatigue failure.
