Abstract

Abstract:

The changes of flow field and temperature field for wax droplet formation process by external periodic sinusoidal disturbance are studied based on computational fluid dynamics software FLUENT. The morphology of droplets at different disturbance frequencies is simulated, and the uniform droplet stream is obtained. By simulation, it is known that the disturbance frequency has a good effect on the droplet formation and its uniformity. The numerical results agree well with the experimental ones in the literature.
