A computational fluid dynamics (CFD) simulation was developed to model heat transfer of sixblocks of agar in a forced air chilling process. The flow field was solved at steady-state anddecoupled from the heat transfer processes. The six blocks of agar were placed in a polystyrenetest chamber that mimics the airflow and product arrangement in an industrial cheese chillingtunnel. Temperatures were measured at the surfaces and the geometric centre of the tested blocksof agar. Good agreement was observed between predicted and experimental data. The local heattransfer coefficient across blocks of agar surface varied by a factor of five at the high air velocity.
