ABSTRACT:
The apparatus and method herein provides for the calculation of shape factors and transfer factors of any object, particularly useful in radiative heat transfer analysis. The object sought to be characterized can be a model of full sized. A radiometer measures the light flux from various surfaces of an object, and a computer is used to assign each flux to a finitely preselected area. After all of the surfaces of the object have been measured and accounted for, the computer is than enabled to compute the shape factor of the object utilizing the relationships stated in the disclosure. Techniques of measurement include illumination/draping, electroluminescent panels, and projective illumination.
