there is some dvd's from gnomon or digital tutors talking about fluids and probably that.
If your camera don't move, i suggest you to start with the nuke 2d and try to improve it, fluid are often a lot of "cooking time"
check the texture, replace the blast on the ground by an other rendering... finish it in comp, don't try having the perfect render directly in maya, go the best you can and use multiples diffrents render to mix and having a better result.
good luck
