Temperature control in a reactor

Hi everybody,
I am a beginner in COMSOL and I am wondering if you can help me with one simulation. I measure the temperature at the bottom of my reactor and I need to control that temperature (in this point) adding heat flow which is constant throughout the reactor (as a proccess control), how can I do that?
Thanks!

Hi

look up the examples, there was one of those, or very close, at least in the 3.5a (perhaps not yet ported to v4.1, check the "Options - model browser update - Download all"

Good luck

hi dear
I am working with this software and I am beginner and working about reactors.
I'm student of petrochemical engineering.
can you send me some examples about fixed bed reactors?
If you don't have any example about fixed bed reactors please sent me some useful and simple examples about reactors.note that the documentation in the this software don't help me.
thanks

Hi

sorry I'n not really in that field, so I have no models myself, or at hand, apart from those in the model libray of COMSOL (be sure you have updated in v4)

My way to apprach is to take one step at the time, identify the physics needed, flow, diffudion, chemical exchange ... and treat some simple examples, then to combine two, three etc physics, mostly your model builds up nicely, at least faster than when you start by mixing everaything at once, and then do not really know what is driving what, or what might be missing in case of errors

Hi
thanks Mr Ivar Kjelberg
If you have any related examples except which is in the comsol 4 or 3 please send to me.
I don't know how to apply the kinetic of the chemical reaction?
