Maintaining average temperature at Inlet in cyclic Boundary condition
Dear all,
I want to maintain the average temperature at the inlet to fixed value of 1 in my cyclic boundary condition. (streamwise periodic heat transfer) I have seen the fvOption utility patchMeanVelocityForce to fix the average velocity at any patch to desired value. Is there any utility available in OpenFOAM to fix the average temperature of any patch? Thanks in advance:) |
Maintaining average temperature at Inlet in cyclic Boundary condition
Since i am not dealing with actual temperature and my temperature range is from 0 to 1, this can be implemented in OpenFOAM very easily by following way.
In some cases people suggest this procedure after every N time step rather than every time step. This N can be found by trial and error. If we don't fix average temperature at INLET to a constant value, temperature value inside the domain can go to very very low value (Cold walls + hot fluid entering case) or very very high value (Hot walls + cold fluid entering case). This is because of the cyclic boundary condition applied at INLET and OUTLET. Please correct me if i am wrong:o |
Hello Luttappy,
did you find out how to set the value for the temperatur with a cyclic inlet boundary condition? Greetings |

Me too please!
I have a non-uniform cross section periodic channel that this may work for. Sharing your solution would be very helpful... Regards Peter |
