VCE Overpressure Prediction by CFD Modelling

  • Chapter
  • First Online:
Risk Analysis of Vapour Cloud Explosions for Oil and Gas Facilities

Abstract

This chapter explores the mechanism of gas explosion and demonstrates its computational fluid dynamic (CFD) simulation procedure. The fundamental partial differential equations, which govern the fluid flow and other explosion processes employed in the numerical models for calculation of VCEs, are presented. FLACS is adopted for the evaluation of the potential VCEs in oil and gas industries. The CFD simulation theories in FLACS regarding the flame turbulence, geometry condition and fluid–obstacle interaction, etc., are discussed. The flow chart for the simulation procedure along with gas explosion examples is given.
