Channel Height And Wall Effects On Surface Htc In A Narrow Impingement Channel

Abstract

This paper examines the local and averaged effects of channel height in the presence of side walls on heat transfer coefficients, with special attention given to the side wall heat transfer coefficient. High resolution local heat transfer coefficient distributions on target and side wall surfaces were measured using temperature sensitive paint and recorded via a scientific grade charge-coupled device (CCD) camera, and compared to available literature. Streamwise pressure distributions were recorded and used to explain heat transfer trends and to determine the thermal efficiency of each channel. Results are presented for average jet based Reynolds numbers between 17,000 and 45,000. All experiments were carried out on a large scale single row, 15 hole impingement channel, with X/D of 5, Y/D of 4, and Z/D of 1, 3 and 5.
