Parametric analysis of the airflow performance of ventilators.

Author(s) : SHARPLES S., CHILENGWE N.

Summary

In this study a parametric analysis was carried out on the interaction between louvres and various perforated mesh screens. An airflow testing rig was used to examine the impact on the louvre airflow performance of the meshes. The interaction between louvre geometries and blade inclinations with meshes of different hole sizes was also investigated experimentally. Initial results indicate that at low pressure differences the small diameter (less than 5 mm) meshes were producing a discernible reduction in the airflow, but that at larger mesh diameters (15 mm) the loss was much less significant. The suitability of CFD software to predict the mesh/louvre interactions was also investigated.
