To solve the problem of lubrication failure of MMA in aerospace

drop-on-demand technology(DOD) was applied to the lubricating oil active complement system for space mechanisms.Using the simulation software of CFD-ACE

combining the computational fluid dynamics theory with the volume-of-fluid method along with the piecewise linear interface construction technique

injection process simulation that the liquid injecting into the thin air from a contracting nozzle was carried out.Experiments were conducted to det...
