Résumé

This paper examines the aerodynamic behavior of a plane wall jet exposed to a lateral perturbing flow. The key benefit of this investigation is to bring new knowledge which helps in designing better air curtains operating in disturbed environments. For this purpose, a new experimental setup is achieved which consists of one-fifth scale model of a real refrigerated display cabinet (RDC) enabling the control of the ambiance, the cavity (zero-depth in the present paper) and the jet. PIV measurements of the flow development characteristics such as mean velocity, spread and decay rate have been performed. Results show the role of the perturbing lateral flow in the reduction of engulfed ambient air into the air curtain. Instantaneous PIV results show that the perturbed flow strongly affect the formation, development process and frequency shedding of Kelvin-Helmholtz vortices in the shear layer in the near field region.
