Computer Fluid Dynamics Analysis of Cryogenic Oil Mist and Structural Optimization of Spraying Nozzle

Abstract:

An investigation of the cryogenic oil mist flow field of nozzle was carried out in this study. A domain of the nozzle jet area was modeled with Pro/ENGINEER. CFD (Computational Fluid Dynamics) analysis was used to state the velocity field of different distances from the outlet of nozzle. The simulating velocity field was verified with the experimental results. Experimental results on velocity were measured by SYT-2000 digital multipurpose wind speed gage. The orthogonal experiment was designed to investigate the main effects parameters on velocity and temperature. It indicates that higher flow of cold air and smaller diameter of nozzle’s outlet will generate higher velocity. The temperature of cold air has most influence on the temperature of measuring point. Finally the optimum structure of the spraying nozzle was proposed.
