setting up temperature profile in a reactor

July 1, 2002, 12:46

hi everyone,

can any one help me with establishing the following profile through out a reactor domain, reactor length = 157cm T1 = 900 - 1400k l = 0 to 16 cm T2 = 1400k l = 16 to 44 cm T3 = 1400 - 700k l = 44 to 60 cm T4 = 700k l = 60 to 157 cm i have tried some methods but wouldn't work, so any suggestions would be greatly appreciated. thanks in advance for the help. sivakumar

Hello,

what exactly do you want? Is this a piece-wise 1D temperature profile inside your reactor? Is this a wall temperature?

hi laika, this is a 1-D temperature profile within the computational domain. i would greatly appreciate it if you could help me. thank you, sivakumar

You can patch in your temperatures in separate fluid zones defined to match the profile range you previously described. Then turn off the solution of the energy equation.

I agree, that's the way to do it.
