| Abstract: | A method for analyzing the rotating turbulence boundary layer flow was presented. A two equation turbulence model was employed with modification to include the influence of Corio-lis force and adverse pressure gradient. Relationship between Poc and Re has been found by computation. As a result, the inverse transition criterion has been given. |
