Description Paper from the AFRC 2015 conference titled Radiation Effects on Surrounding Structures from Multi-Point Ground Flares
Abstract A Multi-Point Ground Flare (MPGF) was modeled at various flow conditions with a 9 m/s wind. This MPGF consists of 15 stages and 341 flare tips and is capable of flaring in excess of 2x106 lb/hr of vented gas. The detailed computational fluid dynamics (CFD) model of this MPGF was developed using a proprietary flare modeling tool called C3d. This study emphasized the flare plume and its effects on nearby structures. A low-flow unignited case was also run to examine the size of the flammability cloud that would form. The simulation predicted that for the unignited case the flammability cloud comes close to some nearby structures. The MPGF fence does perform well in shielding structures from radiation, reducing radiation levels by a factor of 3 or more but with the wind forcing the plume in their direction closer structures are still receiving radiation fluxes of as high as 3000 BTU/hr◦ft2. The results of this MPGF CFD study have been used to help finalize design of the MPGF in general and the fence specifically.
