Effect of the Direction of Coolant Supply to Holes on the Vortical Structures Formed in Screen Cooling
RÉSUMÉ
The results of an experimental investigation of screen cooling of a plate for two variants of coolant supply to holes is considered: when a coolant flows parallel to the main stream and when it flows normally to the main stream. The experiments were carried out with the aid of a nonstationary technique using liquid crystal heat-indicators. The experimental data were processed with the aid of the least squares methods. The paper presents the results of numerical simulation of screen flow in the case of a normal direction of coolant flow relative to the main stream direction. The numerical simulation made it possible to reveal a complex structure of the coolant flow (of vortical nature) in a perforation hole.
