The augmentation of local mass transfer ainong the turbulence promoters was measured by varying the diameter, the pitch of the promoters and the clearance between the promoters and the wall. In order to examine the augmentation mechanism, wall shear stress, mass transfer intensity and turbulence intensity at the wall were measured by an electrochemical method. Further, flow behaviors were measured by visualization. It was found phenomenologically that the augmentation of mass transfer with the clearance was caused by turbulence due to reattachment flow, large scale eddies and increase of shear stress due to flow jet under the promoters and was caused by only turbulence on the wall surface in case of no clearance., Article, 富山大学工学部紀要,36, 10-22.(1985)}, pages = {10--22}, title = {Augmentation Mechanism of Mass Transfer Among Turbulence Prompters on Wall Surface in Rectangular Duct}, volume = {36}, year = {1985} }
