Amir Filipovic Guest Posts: n/a	Hi, I'm trying to develop a 1D model for smoke transport in tunnel and have some problems with the gravity term. I've tried the Boussinesq approximation, where this term appears in the momentum equation, without success. If anybody could give me a hint or reccomend a book/article where this is well explained, I would be very grateful. Thanks in advance. Amir
