Dear all,

Can i introduce a temperature excess in the velocity inlet? and How?

Thanks in advance.

Adrian

can you define the meaning of temperature excess?

i mean a higher temperature of a jet injecting into an ambient with lower temperature

If I understand, you have a domain with a temperature, and And you have a jet coming out of an inlet with a different temperature...

if this is so, fix the temperature of the velocity inlet at the jet temperature..., fix the temeprature of the boundaries of your domain at the ambient temperature...

Yep that's what i want thanks ~~

But for velocity-inlet B.C., there's no temperature option, where can I set their temperature?

I think you forgot to turn on the energy equation...

define-> model-> energy

then go back to your velocity inlet BC...you should see the temperature

THank You
