Tollmien-Schlichting flow transition in 3D rectangular channel
Hi
I'm working on a turbulent 3D rectangular channel flow in order to point out the transition at Re=5772 tollmien-schlichting waves, until now, i've build several models but none of them succeeded in developing tollmien-schlichting waves around Re~5772, i'm performing calculations with Fluent 13 on i7 8gb ram, here is the model summary: -Channel dimensions: 250 cm x 60 cm x 2 cm 1080000 cells / boundary layer mesh -Water -sst k-w with 100 to 200 roughness height -Turbulent inlet condition: set the intensity to 5% and length scale to 0.01 m -Solver to second order in momentum Could someone please give me guidelines to modify the model in order get to Tollmien-Schlichting waves transition pattern ? Thanks in advance, help and suggestions will be really appreciated. |
