Patent ID: 8626478

Claim:
A computer implemented method for determining a cross flow angle for a feature on a structure, wherein the feature comprises one of a cavity in the structure and a gap filler on the structure, the method comprising: receiving, by a processor, location information identifying a location of the feature on the structure; determining, by the processor, an angle of the feature; identifying, by the processor, flow information for the location, the flow information describing a flow of fluid across the structure; determining, by the processor, a flow angle using the flow information, the flow angle comprising an angle of the flow of fluid across the structure for the location of the feature; and determining, by the processor, the cross flow angle for the feature using the flow angle and the angle of the feature, wherein the cross flow angle comprises a first angle between a direction of the flow of the fluid across the structure and a second angle of the cavity or the gap filler.
