  • Patent number: 7120544
    Abstract: A method for analyzing a turbulent fluid flow field includes the steps of: creating a mathematical model of a physical object; simulating a flow field around the model, wherein the flow field is at least partially turbulent; generating time series flow data output data representative of the flow field; and identifying repeating turbulent flow patterns in the flow data. These features are identified by selecting at least one frequency range of interest; filtering the flow data based on the frequency range; and observing coherent structure in the filtered data. The method may be implemented as a software program running on a computer.
