For the different wall of greenhouse including the cover where they are exposed to solar radiation, exchange different way of heat flux (radiation, convection, conduction, condensation....). for these heat flux, we need many correlations for defined the coefficient heat transfer and other parameters. I want to know, can I used the same correlation of different wall and cover).
Hi,
I think it is a kind of similarity.
You can apply to different wall and cover if you can keep the similarity criteria between two systems.
In similarity theory, the two systems can be considered as similar if they have similar dimensionless parameters such as Re, Nu, Gr, Pr, etc.
I hope it helps.
Dear Son.
Thanks a lot for your interesting answer. Me too I thank that too but I ask why many authors interest of heat in cover more than the other well? in addition they make different correlations for the cover and the other wall of greenhouse ..
Best Regards
Thanks a lot dear Dr. Hidouri. I'm asking this question after review a different description in thermal behaviour for doffeebt authors interest of this topic. As it's explain above we can take the same correlations for different walls and cover as we can't doing that if they Aren't exposed in same way for solar radiation.
Maybe for simplified our sytem it's benific to take same correlation.
Cordially
