Abstract
The vortex tube which is used to separate the dust of air flowing into engine could reduce or eliminate the damage of dust to engine and guarantee running security. The paper presents resistance characteristic and separation efficiency of vortex tube through Navier-Stokes equation and standard k - epsilon turbulence model. The influence of SCR (scavenge ratio) and main flow to total pressure loss and main flow, restitution coefficient and SCR to the separation efficiency are obtained by numerical simulation. Resistance characteristic obtained by numerical simulation is well consistent with experiment which declares the numerical computation method described here could indicate resistance characteristic of vortex tube in high precision.
