Influence of air duct systems on airflow and temperature dispersion in a truck.

Author(s) : MOUREH J., FLICK D.

Summary

This work is part of a research activity aiming to improve and to optimize air distribution systems in refrigerated vehicles in order to decrease the temperature differences throughout the palletised cargo. This condition is essential in order to preserve the quality, safety and shelf life of perishable products. The study reports on the numerical and experimental characterization of airflow within a semi-trailer enclosure loaded with pallets. The experiments were carried out on a reduced-scale model built with a ratio 1/3.3 of a trailer. The numerical modelling of airflow was performed using the computational fluid dynamics code fluent with the Reynolds stress model (RSM). The performance of ventilation and temperature homogeneity were characterized with and without supply air duct systems. Both configurations were extensively used in refrigerated transport.
