Abstract : Mean velocities, turbulence intensities, and Reynolds stresses were measured in a circular convex wall jet. The entire mean velocity profile for angular position (theta > 35 degrees) was determined to be similar. The turbulent flow field was nowhere self preserving and thus the total flow was not similar. Strikingly different jet growth rates were evidenced between the inlet (theta > 35 degrees) transition region and the fully developed flow regions (theta > 35 degrees). The overall level of turbulence was examined for a convex wall jet flow in comparison to a concave wall jet flow. The turbulent shear stress's were observed and did not vanish where the mean velocity gradient became zero. Hence for further analyses of turbulent convex wall jet flow the classical eddy viscosity models which neglect the effects of curvature appear inappropriate.
