Standard methods exist at NIST for calibrating thermal radiation detectors up to 10kW/m2 using blackbody cavities, and up to 40 kW/m2 using a monochromatic laser source. Heat flux transducers, however, are often used under conditions where convection dominates, where radiation emanates from a source with a different spectral character, or where flux levels exceed 40 kW/m2. The objective of this project is to extend NIST heat flux calibration capabilities to, at least, a limited range of the latter conditions. Convective and conductive heat transfer facilities are being designed and constructed for this purpose.
