Description

This paper presents a practical thermal circuit method for calculating the R-value for a composite wall with enclosed air filled rectangular cavities. Simultaneous effects of convection and radiation on heat transfer are considered. In addition, a parametric study is performed to investigate the effect of geometric arrangement and surface emissivity on the R-value.
