have developed a mathematical model to calculate the shortwave optical properties for a curved slat venetian blind with thickness and a mathematical model to calculate the longwave optical properties for a curve slat venetian blind by including both the effect of slat curvature and the effect of slat thickness in the mathematical model.
With an accurate model for the optical properties of the curved venetian blind, the thermal performance of the glass window with a curved venetian blind installed can be accurately predicted.
