COUPLING STUDY BETWEEN HEAT TRANSFER AND AERODYNAMIC FLOW IN SQUARE-EDGED INLET

SINOPSIS
This work presents an experimental study pertaining to coupling between heat transfer and aerodynamic flow in pipes with a square-edged inlet simulating the perforation of a multiperforated wall. The experiments were performed for a range of Reynolds numbers from 8000 to 35000 and an aspect ratio from 2 to 8. The results showed clearly the coupling between heat transfer and aerodynamic flow. These results achieved have allowed us to characterize the different flow areas within the pipe: takeoff, landing, and developed; they have also enabled us to highlight the influence of aero-thermal and geometric (l /d) parameters.
