Patent ID: 8099265

Claim:
A method for determining and displaying fluid flow in a bounded space, comprising: employing at least one processor for: defining a set of reference velocity fields sustained within said bounded space, each reference velocity field having a respective one of specified directions; determining a set of incremental velocity fields corresponding to said reference velocity fields, for each of a number of predefined speed values of said reference velocity fields, caused by placing an object within said bounded space; inducing a specified velocity field within said bounded space; determining perturbation of said specified velocity field, caused by placing said object at a specific position within said bounded space, by performing an interpolation process based on said reference velocity fields, said set of incremental velocity fields, and a representative velocity vector of said specified velocity field at said specific position; representing each said incremental velocity field by incremental velocity vectors at each sampling point of a plurality of sampling points within said bounded space; determining said incremental velocity vectors at each of said sampling points and retaining only each incremental velocity vectors having a magnitude exceeding a predefined threshold; and presenting said specified velocity field and said perturbation of said specified velocity to a display module.
