CFD modeling and fire damage analysis of jet fire on hydrogen pipeline in a pipe rack structure

Abstract

The fire accident to most frequently occur at a process plant may be generated at any place transporting or handling combustible materials. Especially, in the case of a jet fire at a process plant pipe operated under high pressure, a critical outcome may arise. To review this, this study was designed to apply the CFD simulation on the outcome of a jet fire generated at a high pressure hydrogen pipeline within a pipe rack structure to compute the consequences. For the simulation, Kameleon FireEx(KFX) was used, and for results, the temperature of a jet fire and heat flux distribution under the complex geometry of a pipe rack structure, boundary conditions, and turbulent combustion were reviewed.
