N-butylnitroxyethylnitramine (BuNENA) is a high-energy plasticizer with high plasticizing ability, low sensitivity, and energy. It has broad application prospects in HTPE propellants. Nevertheless, as an energetic plasticizer, it requires treatment to reduce its sensitivity. To this end, the passivation process for BuNENA was simulated using mixing model analogous nucleate boiling. This method involves tracking formation movement of bubbles Lagrange frame, themselves are modeled rigid spheres subject buoyancy viscous forces. A variational multiscale (VMS)-based Euler framework employed simulate fluid surrounding bubble. The analyzed, found that amount speed were higher at temperatures vacuum, effect on better. At pressure 40 mbar temperature 50 °C, demonstrated 89% water removal rate. comparison experimental results simulation revealed slight discrepancies between them. meticulous analysis rendered possible by integrating methodologies, feat immense implications realm composite solid propellant passivation.
