Molecular Dynamics Simulations of Supercritical Jets

摘要

In a previous report, we have presented the argon nanojet injection simulation results under vacuum condition. This study also focused on the effect of injector shape on jet breakup behavior. However, geometrical effects were not so prominent. After a thorough analysis, we concluded that the temperature of the liquid in the solid injector is the governing factor for subsequent nanojet breakup characteristics. We will introduce this conclusion with detailed description in the following section. In addition, the previous nanojet injection code was modified for injection under sub/supercritical pressure. These results will also be presented later in this report.
