Study on the Effect of Nozzle Parameters on Annular Flow in Oil-Air Lubrication
Based on the formation mechanism of two-phase flow in oil-air lubrication, the flow field of annular flow through the nozzle is simulated by the computational fluid dynamics software CFD. Study on the effect of different system parameters and structural parameters on the flow field of oil-air annular flow. According to the characteristics of oil-air lubrication, the optimum nozzle structure parameters are determined. Study on flow pattern change of oil-gas two-phase flow through nozzle in limited space and infinite space, analysis the flow field characteristics of oil and air two-phase flow after leaving the nozzle.
