衝撃波によるエアロゾル形成の数値シミュレーション

抄録

Shock and detonation waves due to the explosion is caused by the rapid change in pressure. When these waves propagate across a layer of liquid, a portion of the liquid turned into fog that is called as aerosol. Aerosol is very light and readily diffuse into the atmosphere. If the aerosol contains hazardous materials, such as the radioactive materials and toxic substances, it may cause serious environmental pollution especially to the soil and health risk to the human. Thus, this is an important issue to be solved in the safety analysis. However, it may possible to alleviate this risk if we have a detailed insight about the shock-induced aerosol formation. In this study, the interaction between shockwave and water surface is simulated, and CFD analyses are performed to investigate the flow features and aerosol formation. The compressibleInterFoam solver of OpenFOAM is used to simulate this problem.
