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

Candanedo, L. M., Athienitis, A., Candanedo, J., O?Brien, W., Chen, Y.,
(2010). Transient and Steady State Models for Open-Loop Air-Based BIPV/T
Systems. ASHRAE Transactions. Vol 116. P. 600-612.

I hope it helps,

Luis
