Accuracy And Computational Cost Assessment Of Radiation Solvers For Combustion Simulations, Chloe David

Master's Theses (2009 -)

High-fidelity combustion simulations necessitate the accurate and efficient calculation of radiative heat transfer. A successful radiation calculation requires the use of a spectral model, which describes the variation of radiative properties across the entire electromagnetic spectrum, and a radiative transfer equation (RTE) solver, which solves the governing equation for radiation transport. Three primary categories of RTE solvers are the discrete ordinates method (DOM), the spherical harmonics method (SHM), and the photon Monte Carlo (PMC) method. The accuracy and computational cost of each type of RTE solver is compared in detail in this work. The PMC RTE solver is considered the …
