ANSYS Fluent Tutorial | Water Hammer Simulation in Pipeline

In this video tutorial you will see:
1. How to make CFD domian of pipe for simulation in Design Modeler
2. How to generate of the mesh in Meshing
3. How to set up boundary condition and simulation in Fluent
3.1 Creation of the time dependent boundary condition for velocity
3.2 Creation monitor points for watching to the flow parameters
3.3. Set up transient simulation

It was so helpful for my research. Thank u and good luck.

Hi, how can we simulate a realistic valve closure in Ansys ? Thank you.

[@abdelrahmanamr9758]

how can i get (named Expressions) in ansys 18 or ansys 19.2 ?? i can't find a place to write the function as demonstrated

Why does pressure below -101325Pa come out? As far as I know, the gauge pressure cannot come out below -101325Pa.

[@tarunshriyan4967]

Do you have any research paper regarding the experiment that youve performed

[@benclimbing]

Great video. You're essentially showing an instantaneous closure, but is there some way to do this with a valve closure time that is more realistic? Thanks

Hi have you found a way to simulate a more realistic valve closure ? Thank you.

I'm from Perú, i wanted use it, in 2017.

[@MrDuonghuong1991]

why gauge pressure (initial pressure)= 101325 pascal anh here operating pressure =101325 pascal or 0?. thanks

[@CFDIntech]

initial pressure = 101325 Pa because we have operating pressure = 101325, for faster convergance.

[@amirziaee5492]

@@CFDIntech Do we have pressure of 101325 pa relative to atmosphere?

[@aravinthkamaraj521]

can you show us the contours?

[@CFDIntech]

Hello, what contours do you want to see?

@@aravinthkamaraj521 This is transient, monitor points with pressure more informative than contour, you can make this tutorial and will create contour)
