	  abstract     = {The reliable results of an insulated oval duct
considering heat radiation are obtained basing on accurate oval
perimeter obtained by integral method as well as one-dimensional
Plane Wedge Thermal Resistance (PWTR) model. This is an extension
study of former paper of insulated oval duct neglecting heat radiation.
It is found that in the practical situations with long-short-axes ratio a/b
<= 5/1, heat transfer rate errors are within 1.2 % by comparing with
accurate two-dimensional numerical solutions for most practical
dimensionless insulated thickness (t/R2 <= 0.5). On the contrary,
neglecting the heat radiation effect is likely to produce very big heat
transfer rate errors of non-insulated (E>43% at t/R2=0) and
thin-insulated (E>4.5% while t/R2<= 0.1) oval ducts in situations of
ambient air with lower external convection heat coefficients and larger
surface emissivity.},
