| Popis: | International Congress of Refrigeration , Beijing, CHN, 21-/08/2007 - 26/08/2007; International audience; This work is part of a research activity aiming to improve and to optimise air-distribution systems in refrigerated vehicles in order to decrease the temperature differences throughout the palletised cargos. In this paper, a reduced -scale model and CFD predictions were used to investigate experimentally and numerically the airflow patterns within a typical refrigerated truck configuration loaded with vented pallets filled with spherical objects. The experiments were carried out using a laser Doppler velocimeter and thermal sphere-shaped probes located inside the pallets. The aim was to investigate air velocity characteristics above and within pallets. The performance of ventilation was characterized with and without supply air duct systems. The numerical modelling of airflow was performed using the Computational Fluid Dynamics (CFD) Fluent code and the Reynolds Stress Model (RSM) turbulence model. Numerical and experimental data confirm the benefits of air ducts in reducing the heterogeneity of air ventilation levels above and within the pallets. |
