Abstract：Freezing and blockage resulting from the deposition of solid CO₂ formed because of sudden expansion of the downstream pipe during the release of CO₂ through safety valves, will endanger the protected equipment. To overcome this problem, the characteristics of the CO₂ gas-solid sudden expansion flow are studied by using the disperse Lagrangian model. A comparison of the calculated deposition of the solid CO₂ with the experimental results shows that they are in reasonable agreement. The simulation results show that the size of the solid CO₂ formed should not be in the range of 0.04–0.07 mm (St number 3.2–9.8). This can be achieved by using an appropriate flow cross section of the safety valve.
