Hello every one,
Hope you are all doing great. I have a question. Actually I am evaluating the effect of the setting parameters (pressure, temperature, velocity and viscosity) on the flow behavior( for instanced longitudinal and transversal roll). For instance, I saw that when I increased the velocity in Ansys Fluent, the roll type flow appeared, but when I increased the pressure the change on the flow pattern was very intangible( minor). Actually all of my result comes from my observation. For example, by looking at the vectors, I figured out the pressure did no have much effect on the flow behavior. Because I did not see much change. My question is that is it any other criteria other than observation of the vectors? Would you please give me some suggestion? Thanks in advance, |

It seems that you are newbye in CFD!! There are some parameters which should be checked such as: shear stress at the wall, pressure distribution along the pipe, average velocity or core velocity along the pipe, heat flux at the wall (if energy is solved), y+ value along the wall (if flow is turbulent) and so on. Goodluck. |
