Estimation of dimensionless temperature distributions in spherical products during hydrocooling

Experiments and computations were performed for temperature distributions within a single spherical product cooled in water flow. Experimental center, half radius and surface temperature distributions of the individual tomatoes during cooling at a water temperature of 1 °C and a flow velocity of 0.05 m/s were measured. The heat transfer coefficients determined by Dincer model for a single product were used in the computations. Comparisons between experimental results and theoretical predictions were observed in a very good agreement form.
