A method of quantitative non-destructive thermal inspection of a three-dimensional article having at least one three-dimensional internal cavity comprising the steps of:
- inputting physical properties of said article, wherein said physical properties comprise three-dimensional parameters;
- measuring thermal characteristics of said article;
- and
- calculating heat transfer coefficients of said at least one three-dimensional internal cavity, wherein said calculating heat transfer coefficients accounts for said three-dimensional parameters.
A method of determining internal HTC's of a three-dimensional article having at least one three-dimensional internal cavity comprising the steps of:
- measuring thermal characteristics of said article;
- computing local temperatures of a working fluid introduced within said at least one internal cavity;
- inputting physical properties of said article, wherein said physical properties comprise three-dimensional parameters;
- and
- calculating heat transfer coefficients of said at least one three-dimensional internal cavity, wherein said calculating heat transfer coefficients accounts for said three-dimensional parameters.
A method of non-destructive thermal inspection comprising the steps of:
- inputting physical properties of an article, wherein said physical properties comprise three-dimensional parameters;
- measuring thermal characteristics of said article;
- and
- comparing said thermal characteristics of said article to baseline thermal characteristics.
