Dear Flow3d users,
I have some question about the shear stress calculation in the closed channel flow. I have a rectangular channel section and the water flows from left to right. I have used the periodic boundary conditions. I want to know the shear stress on the walls. In the software itself I didn't find any option to extract the shear stress. Is there any option to calculate shear stress, then would you good people please let me know ? If there is not any option, then I think we have a equation of shear stress as follows: Tou (shear stress) = neu * (du/dy) neu= dynamic viscosity. HOw do we use this equation with the output from Flow3d to calculate shear stress ? Any help is highly appreciated. THank you. |

Beginning in v9.4 of the software shear stress is an available output (as 'Excess Shear Stress', for which the threshold can be zero if total shear is desired).

You can also output the total (integrated) shear force on the channel if you ask for this output option in the input file. This option is available for each geometry component.

Hi everybody,
Is there any way to calculate the shear stress in flow-3d ver. 9.3.2? |

Salam Maziar,
I do not understand what do you want to do? Do you want to model the shear stress in FLUENT? or Flow 3D? Farhad, |

You can easily see wall shear stress by this way,
Fluent ---> Graphics and Animations ---> Contours ---> Wall Fluxes |
