Re: Boundary Condition

I not sure about the exchange coefficient means convective heat transfer coefficient, h or can be treated as overall heat transfer coefficient, U?

Re: Boundary Condition

Hi, thank you for your reply. If the boundary condition (wall) is made up of composite material, can I treat the exchange coefficient as overall heat transfer coefficient, U as it also has same unit W/m2.K?

Boundary Condition

In the boundary conditions section, for the exchange coefficient, is it means the thermal conductivity? Currently, i am doing ventilation problem, for the composite wall material, I calculate the total heat resistance by using formula R=1/hA+L/kx then convert to overall heat transfer coefficient, U....

Re: How to plot residuals in Windows?

Dear xingjian,

I would like to seek your help on how you plot these probe_Temp file in which by setting x is the time step while y is the temperature?

Thank you.
Regards,

Hao

Radiative Heat Transfer

Dear all, Does anyone has the manual on using the radiative heat transfer and conjugate heat transfer command in code saturne? CurrentlyI am doing the ventilation within shipping container house and would like to add the heat transfer through radiation in the calculation for better accuracy. One mor...
