Hi Leen,
I did my PhD work on Building Integrated Photovoltaic/Thermal systems.
My work was mostly focused at the interior convective heat transfer coefficients in the cavity/gap between PV modules and the next layer of building envelope in the roof where the air flowed.
However I looked numerically the influence of different wind correlations:
Hi Leen,
I did my PhD work on Building Integrated Photovoltaic/Thermal systems.
My
work was mostly focused at the interior convective heat transfer
coefficients in the cavity/gap between PV modules and the next layer of
building envelope in the roof where the air flowed.
However I looked numerically the influence of different wind correlations:
Test et al. (1981), Sharples and Charlesworth (1998), McAdams (McAdams, W.H.,
1954; Duffie, J.A. & Beckman, W.A.,
2006) as a function of the wind speed in m/s:
ho = 8.55
+ 2.56
?Vwind
ho =11.9+2.2?Vwind
h=5.7+3.8Vwind
and also I used a correction factor for the Wind speed at the height of my experimental setup.
(Hutcheon, Handegord, 1995)
Vwind=Vg(Z/Zg)^alphawind
In general I found that the Sharples and Charlesworth correlations gave me the best results.
You can look at my thesis and this paper

I hope it helps,
