Modified Structure Function Model Based on Coherent Structures |
|
| چکیده انگلیسی مقاله |
In the present study, a modified Structure Function was introduced. In this modified Structure Function model, the coefficient of model was computed dynamically base on the coherent structure in the flow field. The ability of this Modified Structure Function was investigated for complex flow over a square cylinder in free stream and a low aspect ratio cylinder confined in a channel. The Results was compared with experimental data, standard structure function and Coherent Structure Model which use a dynamically method to computed the coefficient of Smagorinsky model based on coherent structure in the flow field. The results show that Modified Structure Function improved the stability and accuracy of simulation in comparison to Coherent Structure Model and standard structure function model |
