文摘
- •
We developed an E-EWB model to calculate the absorption coefficient.
- •
Total emissivity obtained by the EWB and LBL models will deviate at low temperature.
- •
The E-EWB model is more accurate than the EWB model.
- •
The calculation speed of the E-EWB model is about 350 times faster than that of the EWB model.
- •
The E-EWB model is prospective to be used in the CFD calculation.
