coefficient development lead to understanding the unsteady nature of tunnel kiln behavior
during cooling. The present paper introduces experimental investigations in a brick tunnel
kiln equipped with a U-shape guide vane to monitor its transient thermal behavior. The
experimental test rig of scale 1: 4 has been fabricated for this purpose. Three U-shape guide
vanes have attack angles (θ= 120°, 135°, and 150°) positioned in the flow direction are used …
