The phenomena and its impact on the adjacent and surrounding equipment are simulated using Computational Fluid Dynamics (CFD) techniques. For the preliminary study, the working fluid used in the simulation is methane. The simulation is linked to appropriate thermal and fluid property estimation software using parameter-tuned equations of state to predict the real multi-component natural gas flow conditions. Through the simulation, a spot of condensation and/or nucleation was predicted. These spots are crucial since their effect appear on the jet simulation in which multiphase properties must be considered. The results showed that the temperature variation on the adjacent surface is divided into three regions, namely: vicinity of stagnation point, sharp variation region, and mild variation region. Such distribution results in inception of thermal stresses that could cause catastrophic incident if rapture occurs. Hence, wall thickness of the equipment that exposed to cold jet should be cautiously selected to sustain the extra thermal stress as well as localised non-uniform stress distribution as detailed in the Finite Element based coupled thermo-mechanical analysis.
