If you need to ask the question your painting skills are not good enough to do.
Painting flames, plumes of smoke, exhausts, beams whooshes etc invariably ends up wrong unless you are a pro-painter. Even then most 'golden demon' level painters wont try it.
As a rule, dont.
There are some exceptions, and armorcast even sells smoke plumes and weapons burst add ons for miniatures. Still it is very very hard to get right.
