Claim Text:
1. A method for measuring mixing of gaseous fluids using thermal imaging, the method comprising: positioning a thermal test medium parallel to a direction of primary flow of a gaseous fluid from an outlet vent of a momentum source, wherein when the momentum source is operating, the gaseous fluid flows across a surface of the thermal test medium; obtaining an ambient temperature value from a baseline thermal image of the surface when no gaseous fluid is flowing from the outlet vent; obtaining at least one operational thermal image of the surface when the gaseous fluid is flowing from the outlet vent across the surface, wherein the gaseous fluid has a temperature different than the ambient temperature; and calculating at least one temperature-difference fraction associated with at least a first position on the surface based on a difference between temperature measurements obtained from the at least one operational thermal image and the ambient temperature value.
