A 6 mm single pane clear glass window and a curved vertical venetian blind are chosen for this study.
The optical properties of the glass window and the curved vertical venetian blind are shown in table 1.
The slat of the blind has a width of 100 mm and thickness of 0.3 mm.
The slat has an angle of the arc length and a radius of curvature as 23.38º and 245.07 mm, respectively.
The slats are separated by a pitch of 80 mm.
The conductivity of the slat is 120 W/m-K.
The blind is installed with a 70 mm distance measured from the inner glass surface to the center of the slat width.
Five slat angles chosen for the simulation are 0, 30, -30, 45 and -45 degree.
The inside room temperature is set at 25 ºC.
The outside temperature is set at 35 ºC.
