Développement d'un capteur mesurant les coefficients de transfert de chaleur locaux sur des objets en forme de carcasse.

Development of a sensor for measuring local heat transfer coefficients on carcass-shaped objects.

Auteurs : HARRIS M. B., LOVATT S. J., WILLIX J.

Résumé

The sensor has an insulated heated surface, whose temperature is automatically controlled in relation to that of the surrounding model surface. The sensor incorporates a device for measuring the free air stream temperature above the model surface. It was initially used in research on the spatial variation in heat transfer coefficient over a carcass surface during air cooling, but can be used with other model shapes. Sensor effectiveness and calibration were verified by inserting it into a heated flat plate constructed from fibreglass and applying a known heat flux to the plate surface, and by conducting tests in a wind tunnel.
