Velocity profile as an velocity intlet condition
how can i use the velocity profile as an velocity inlet condition in fluent
Need help Regards |

Hi
Are you trying to create a velocity profile of your own that has a unique shape? Please provide more detail. Regards AAA |
Re: Velocity profile as an velocity intlet conditi
i am trying to model a pipe in which the velocity profile obtained at the outlet to be used as an inlet condition for a same pipe but smaller in size
yes you can say that i am trying to create a velocity profile (on inlet) that has a unique shape hope i have explained it well i am making a microflow in a microsize pipe for which i want to put the velocity profile at out let to be an inlet condition so that the flow is already developed ... |

Hi
Is this a 2D or 3D case? If the two pipes were of the same diameter, I'd suggest that you go to Define--> Profiles, and write the profile at the outlet in the first pipe. Save it in the same folder that the new pipe exists in. Read this profile in the new case after reading it. In the velocity inlet, Assign the profile to it. When working with two different diameters, I'd read the profile of the large pipe into Excel, cutom it to what I want, putting in mind that I get the right mass flow rate, and then read it again in Fluent. The number of grid points at the two profiles is important. I hope this helps AAA |
