Résumé

The study reports on the numerical and experimental characterization of airflow generated by a wall jet within a long and empty slot-ventilated enclosure. In the configuration investigated, blowing and outlet sections were placed in the front of the box. This design is extensively used in refrigerated transport. Experiments were carried out on a scale model (1:3.3) of a trailer. Numerical modelling of airflow was performed using the computational fluid dynamics Fluent code. In the study, a second-moment closure, the Reynolds stress model (RSM) and two-equation turbulence models, the standard one and a renormalization group, were tested, contrasted and compared with experimental data. It was demonstrated that only the RSM model enabled detection of the presence and the localisation of separated flow and correctly predicts airflow patterns related to primary and secondary recirculation.
