Résumé

A method that allows local heat transfer coefficients to be measured on carcass-shaped objects has been developed. A fibreglass model of an animal carcass was hung in a wind tunnel within an environmental chamber. Controlled temperature water was pumped through the carcass, in order to maintain the surface temperature of the carcass at a desired value. The local heat transfer coefficients were measured by a customised sensor that has been described previously. Heat transfer coefficients could be measured as a function of air velocity, turbulence intensity, and sensor position. By varying the Grashof number, natural convection effects could also be examined. The results of these types of experiments would be useful for examining ways of maximising cooling rates and/or increasing the uniformity of heat transfer rates over the carcass surface. The method has the potential to be implemented in situ within industrial carcass chillers.
