A Thermal Analysis Problem -- CFD Online Discussion Forums

August 4, 2020, 09:07	A Thermal Analysis Problem	#1
Cfdjunior New Member Join Date: Dec 2019 Posts: 17 Rep Power: 6	Hello , I am trying to analyse the heat flow of a simple rectangular domain with a trapezoidal rib inside (Solar Air Heater) in Fluent . I am using periodic B.C's for the inlet and outlet specifying the ambient temperature to be 300K and the rib inside to have a constant heat flux of 1000 W/m^2 . For some reason , I have found parts in the fluid domain that somehow result in a temperature less than 300K . Can anyone please explain or help me to figure out why this happening and if and how i can prevent this
