Heat and mass transfer coefficients at the surface of a pork hindquarter
Hear and mass transfer coefficients were measured at the surface of a pork hindquarter for common air flow properties encountered in chillers and divers. Air velocity and turbulence intensity ranged from 0.4 to 5.0 m s(-1) and 1.3% to 30%, respectively. The local values of the transfer coefficients can be very different from one location to another at the body surface. An inversion of the airflow direction slightly affects the value of the mean transfer coefficients. The effect of turbulence intensity on the mean transfer coefficients is important, but complex and different from what happens on cylinders. An increase in turbulence intensity from 1.3% to 6% decreases the mean transfer coefficients values while a further increase in Tu increases those values. One relation has been established to describe the experimental data for Tu greater than or equal to 6%.
