Iam suppose to calculate vorticity using 3 velocity component u,v and w. Does the built function curl helps to do the job??

Yes it does. See http://en.wikipedia.org/wiki/Vorticity

Is there a way to do it manually. If you help me with formula then i may compute it at least manually. I have V--> Velocity(V), Beta() and yaw. How to compute curl manually using these three variables.

The problem is that I don't know for sure whether your position coordinates are cartesian, cylindrical or spherical. As Roger Stafford points out, they need to be cartesian for the curl function. You might find the functions pol2cart and sph2cart useful for conversions.
