Abstract
A numerical model has been developed of the conjugate convection, conduction, and radiation heat transfer in a double-glazed window with a between-panes venetian-type blind. The two-dimensional finite-volume model has been validated for a range of slat angles using U value measurements from the literature. Data from this solution have been used to show that the thermal performance of the window/blind enclosure can be closely approximated using a simplified model. Such simplified methods of analysis are of utility in fenestration design software.
