| Popis: |
This paper deals with the effect of Newtonian fluid’s viscosity variation on the drop formation through the computational domain. The simulation is performed on a two-dimensional domain and the “volume of fluid” method is used to investigate the impact of dispersed phase fluid’s viscosity on the dynamics of the droplet that expels from a vertical capillary tube. The computational results are validated with the experimental results. Below µ/µw ~ 100, the simulation reveals the linear variation in the dimensionless thread length Li/R. Above this ratio, an exponential increase in the dimensionless thread length is observed. The dimensionless thread length depends strongly on the fluid’s viscosity. Meanwhile, viscosity tends to damp the undulations developed by the breakup of the initial droplet. |
