Relationship between shear stress on the walls of a pipe and an impinging jet

In order to relate a shear stress controlled-corrosion at the impinged jet wall to that in a pipe the pressure drop along a jet tube and the mass transfer rate at eight locations on the jet-impinged wall were measured concurrently using microelectrodes. The shear stress on the impinged jet wall incr...

Summary:In order to relate a shear stress controlled-corrosion at the impinged jet wall to that in a pipe the pressure drop along a jet tube and the mass transfer rate at eight locations on the jet-impinged wall were measured concurrently using microelectrodes. The shear stress on the impinged jet wall increased radially giving stagnation and jet wall regions in the order of 2 and 2.9 times the jet radius, respectively. The mean of the jet-impinged wall shear stresses at all radial positions was 50–120 times that at the pipe wall at any given Re. A factor of about 80 may be used where the jet impinged wall corrosion rates are to be used to estimate corrosion in pipe flow at the same Re.
