I am sorry but I do not know what the question is. If the question is about finite element method, then I suggest that you look at video and web courses available at NPTEL on FEM.
If the question is generally on whether FEM can be used for CFD, the answer is yes. It has been successfully used by many for many problems. However, normally finite element methods are considered to be more difficult to implement and therefore for problems involving complicated physics and thus complicated equations tightly coupled together, one normally uses finite volume or finite difference methods.
Hope this answers the question raised.
