Hi,
I am new to Star CCM+. I took a training at CD_Adapco for the basic introduction classes.

My project is now to analyze the spray characteristics of a Diesel dosing system/ Diesel injector.

A small pictorial description of it is attached in a word document.

Can someone please suggest how to go about this project and what physics model to use and what boundary conditions to use etc..

Main idea behind the project is to analyze the spray (which you see is coming out from the slot). There is a spring actuated valve which when actuated sprays fuel through the slot/nozzle. We need to determine the spray/cone angle, spray droplet size, track the spray particles. The fuel inject is : DIESEL.
