Hello,

I'm trying to simulate a spray injection in a chamber (like in a combustion engine but there is no combustion yet) with a special fuel (special properties of the diesel).

I have created a subroutine (a macro) for the Mass and Heat transfer because my fuel diesel is a special one (I know its porperties). My subroutine is on this link http://dl.free.fr/pyDFeofa6 .

I calculate the depth of penetration of my spray in the chamber but the droplets stay in the extremity of the nozle (for every temperature and every pressure in the chamber).

Why don't the droplets go away ? What is my problem in this subroutine ? (without the subroutine the calculation gives me good results)

Thank you in advance

Best regards
Simon Heintz
