Heat flux meters: Calibration (NT FIRE 050)

Abstract

  This is a method for calibration of heat flux meters which are exposed to a well defined radiation from a radiant heat source. The equipment is designed to minimise influences due to convective heat transfer during calibration. It must be noted that when the instruments are used in practice they will measure a combination of radiant and convective heat transfers. The latter part will depend on the design of the heat flux meter, on local temperature and flow conditions, and on the temperature of the cooling water.
