Hello everyonenif i have an air inlet velocity in transient modeling of solar air heaterni insert the velocity magnitude and temp. of airnnmy question is : will ANSYS consider this inlet temp. constant along the simulation even if i used radiation model with solar load ?.if yes it is constant , how can i make the air inlet temperature change with the time as ambient temperature changes along the day ?n

Hello,nIf you are using a velocity inlet condition and specify the inlet temperature, then Fluent will hold the initial temperature constant through out the simulation.nWhat is your flow condition here? Do you have a stream of flow entering your computational domain? If this is the case, your inlet temperature might not change with time.nThank you.nKarthikn

nThank you for your reply sirni want the inlet temperature to undergo a sinusoidal wave values , how can i make it ?n

Use an expression or DEFINE_PROFILE UDF for the temperature input to the solver. n
