Abstract

The present work deals with the cooling of a plate using an array of staggered round air jets. The aim of the work is to produce a specific database related to the measurement of the convective heat transfer coefficient distribution along the plate. The work is devoted to a particular configuration in which spent air is ejected through holes placed between the jets. The experiments covers the Reynolds number range in [8000, 54000] and a classical thin foil technique associated with infrared thermography was used. This particular configuration is also simulated using the FLUENT 6.0 CFD code. The numerical results are compared to measured local heat transfer coefficients.
