EXPERIMENTAL AND NUMERICAL EVALUATION OF THE KINETIC OF FREEZING BRAZILIAN CODLING (Urophycis brasiliensis) MUSCLE

Abstract

This work carried out an experimental and numerical study of the kinetics of freezing of the Brazilian codling (Urophycis brasiliensis) muscle in air blast freezer, with air temperature set at 253.15 K and the average convective heat transfer coefficient at 25.4 W m-2 K-1. The initial temperature of the fish muscle was 277.15 K and the final temperature 255.15 K. The objective of this work was verify the best agreement between the experimental temperature profile and the numerical temperature profile to Brazilian codling muscle, using the CFD (Computational Fluid Dynamics) as numerical tool. In relation to the obtained results, it was verified that a good agreement between the experimental and numerical temperature profiles for the Brazilian codling muscle. The experimental freezing time found was 6618 s, and the freezing time through the numerical simulation was 6246 s. The error percentage found was 5.6%.
