A method for identifying vortices in a 2-D velocity field is developed. A function based on the local angles of velocity with respect to a datum is calculated at each point in the 2-D field. This function is a local minimum at vortex centres. An advanced statistical technique for identifying multiple minima is used to find the minima of this function. The method is used for vortices, calculated using a RANS CFD code (CFX 4.3), forming around a very large crude carrier (VLCC) and the results are seen to be close to the centres of the vortices.
