1. A thermal inspection method for a component comprising at least one complex internal passage arrangement defining at least one opening, the thermal inspection method comprising:

  • flowing a fluid through the at least one complex internal passage arrangement, wherein the fluid has an initial temperature that differs from an initial temperature of the component;

    measuring a thermal response of the component to the fluid flow;

    analyzing the thermal response to determine a plurality of heat transfer coefficients {hlmn} corresponding to a respective plurality of locations {l,m,n} within the complex internal passage arrangement; and

    using the heat transfer coefficients {hlmn} to determine at least one of (a) a flow rate through respective ones of the at least one opening, and (b) a cross-sectional area for respective ones of the at least one opening.
