Abstract
In this paper, a sensitivity analysis is presented for the equivalent temperature of the incident intensity in applying the full spectrum correlated-k (FSCK) method for liquid fuels. Simulations have been done for radiation penetration within liquid heptane and toluene subjected to incident radiation with equivalent Planck temperature of 500-2000K. Presented relative difference between results of the simulations with and without considering liquid emission revealed the relative importance of the incident intensity and liquid emission for the considered equivalent temperatures. Liquid emission shows a considerable effect on the results for the equivalent Planck incident radiation up to 1300 K and 1400 K for heptane and toluene, respectively. With applying of the equivalent temperature of the incident intensity as the reference temperature in FSCK method, emission of the liquid is not correctly. However, this error does not have significant effect on the overall accuracy of FSCK calculation for the cases with high Planck temperatures of the incident intensity due to the lower relative importance of the liquid emission. However, for the cases subjected to low Planck incident intensity, the error of neglecting liquid emission is significant.
