set a thermal analysis

[stefano.garbin]

on the outer surface impose a temperature.
on the inner surface insert a condition of type "convection", set the temperature of the fluid and the value of the convection coefficient. if you are looking on the net you will find tables with typical values. Watch the measuring units!

ps: I see that you are not very "ferrato" with ansys. I suggest you study these tutorials well:http://www.ozeninc.com/default.asp?ii=84

hi stefano, I just joined the forum just to ask for clarifications on the use of ansys for thermal analysis, since they are at first weapons and the impact with the program is big enough, thank you for the link to the guides :d

thank you stefano, now I try to look at pdf. thank you very much!! !

I'm asking you something in the air.
with the probe command I can detect the temperature on a given point, but when I switch to a different time the probe disappears.
Is there a way to keep the probe or take the temperature at a precise point of the object, so that when I run through the timebar this point does not disappear? ! ?

thanks again:smile:

Hello stefano.
on the outer surface of the tube (in orange) I applied a condition "temperature" while internally a condition "convention".
But I have a doubt. what temperature should I allocate externally to the tube?!? the temperature at which it is located if it does not pass water?!? because the tube is in turn inside a heating body, then absorbs heat.

by convention value, I would need that of water inside a metal duct. I saw that ansys has its own library, but it only contains that of stagnant water. you who have + experience, do you know what coefficient I have to insert for a conduit with inside the moving water? ! ?
thanks again:smile:

stef design... sincerely the problem to finite elements to apply a simple fourier equation.. ? Take back the books of technical physics, don't you?

Okay, but I wanted to do it with ansys wb. Can you explain it to me?
Thank you.
