Effect of Rib Angle on Local Heat/Mass Transfer Distribution in a Two-Pass Rib-Roughened Channel Academic Article uri icon


  • The heat transfer characteristics of turbulent air flow in a two-pass channel were studied via the naphthalene sublimation technique. The test section, which consisted of two straight, square channels joined by a sharp 180 degree turn, resembled the internal cooling passages of gas turbine airfoils. Correlations for the average Sherwood number ratios for individual channel surfaces and for the overall Sherwood number ratios are reported.
