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...

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
