Fluid Injection (Volume of Fluid)

Fluid injections are common in all kinds of products used daily. One common example are the fuel injectors used in internal combustion engines.  ​Simple spray bottles used for cleaning products are another type of fluid injection.

​

For this simulation, a fluid is injected a right angle into a duct with filled air moving at 60 m/s. The two species are tracked using a volume of fluid method in conjunction with a dispersed phase modeling technique. The combination of these two methods is a resource efficient way of resolving the fluid interfaces and converting them into dispersed particles once the "chunks" have become smaller than the grid size.

​

In addition to these techniques, an automated mesh adaptation method was also used to locally refine the fluid interface as it moved through the domain.
