Abstract:

The 3-dimensional turbulent boundary layer produced by a disk rotating in still air was studied theoretically and experimentally. Some of the laws governing 2-dimensional turbulent boundary layers were examined in comparison with 3-dimensional turbulent profiles of a rotating disk. It was shown that a universal description of 2-dimensional turbulent boundary layers by Cornish can be extended to very accurately describe the tangential component of a rotating disk boundary layer. It was shown that a new wake function is required to accurately describe the radial component of the 3-dimensional boundary layer. This function, the crossflow wake function, was developed and combined with Cornishs wall function to give a description of the radial velocity profile. Author
