Radiative heat transfer calculations using full spectrum k-distribution method for benchmark test cases

In the present work, full spectrum k-distribution method (FSK) has been adopted to calculate radiative transfer in presence of participating gaseous medium within an enclosure. The properties is obtained from HITEMP-2010 database. Further, have assembled into a monotonically increasing function using FSK. Moreover, look-up table developed for these at different thermodynamic states and multi-dimensional linear interpolation technique unavailable gases. Furthermore, FSK extended mixture gases mixing models such as superposition, multiplication hybrid models. radiation equation (RTE) solved by finite angle wall heat fluxes divergence flux various test cases categories homogeneous non-homogeneous having conditions temperature mole-fraction. model produces most accurate results among used here. validated against benchmark solution line (LBL). also successfully applied single gas or with almost LBL accuracy extremely less computational cost.
