Abstract
The National Institute of Standards and Technology has developed a convective heat flux calbration facility to allow evaluation of heat flux sensors. This facility is a small wind tunnel that produces a two-dimensionl laminar boundary layer across a heated iso-thermal copper plate. This facility has been developed to allow convection calibration of heat flux sensors to complement heat flux sensor calibrations presently conductd using standard radiation methods, recognizing that many sensors are used in mixed radiation and convection envionments. By extending calibration capabilities to include a primarily convective environment, direct comparisons of sensors in controlled convective and radiative environments are possible. This report describes the first-generation heated plate design, analysis and performance. The reference heat flux on the plate is found from the electrical power input to a guared egion of the plate to the side of the sensor in the spanwise uniform flow.Citation
