Four surface states were considered: as-received, polished, roughened, and as well as that of an annealed sample. Radiative properties and surface profiles were measured by an FTIR spectrometer and optical profilometer, respectively. These measurements were interpreted in the context of a theoretical relationship derived from the Kirchhoff-Helmholtz model. The polished sample most closely matches this theory, and the remaining samples become more aligned with this relationship after large-scale roughness has been removed from the profilograms using a wavelet filter. The results also highlight the fact that E-M wave scattering is dominated by small-scale roughness as opposed to macroscopic artifacts.","PeriodicalId":413005,"journal":{"name":"Proceeding of Proceedings of the 9th International Symposium on Radiative Transfer, RAD-19","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116720082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The radiative characteristics of hot H2O, CO2 and cold hydrocarbon gases were calculated from HITEMP 2010, CDSD-4000 and HITRAN 2016 databases respectively. A simplified radiation reabsorption model was proposed based on the properties of the radiative reabsorption energy at T=1500-2000 K, P=1-100 atm. By using this model, the critical strain rate was calculated for eight C1-C6 hydrocarbon species at T=2000 K, P=1-100 atm. The results show that radiation reabsorption should be taken into account when the strain rate is less than 2.9 s at P=100 atm. The comparison results of the radiation time and the residence time in the CH4 counterflow diffusion flame shows that the radiation time scale would dominate at elevated pressures.","PeriodicalId":413005,"journal":{"name":"Proceeding of Proceedings of the 9th International Symposium on Radiative Transfer, RAD-19","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125083686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, the computational cost of Monte Carlo solvers is an impediment to their use in large-scale simulations. A deterministic samplingbased-quasi-Monte Carlo (QMC) method is proposed in this work as an efficient alternative to conventional Monte Carlo solvers. This QMC uses a low discrepancy sequence instead of random sampling required in Monte Carlo-based approaches. The implementation is validated in onedimensional configurations and is further tested in three-dimensional nonhomogeneous configurations. QMC shows generally better error convergence rates. In three-dimensional cases QMC produces a similar level of error compared to a conventional Monte Carlo solver without having to run multiple statistical instances. This leads to significant computational cost benefits from QMC as seen in the Figure of Merit comparison between QMC and conventional Monte Carlo.","PeriodicalId":413005,"journal":{"name":"Proceeding of Proceedings of the 9th International Symposium on Radiative Transfer, RAD-19","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125602286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combustion chemistry is accounted for by a 16-species chemical mechanism and radiation is captured by a forward Monte Carlo ray tracing solver coupled with a line-by-line model. A backward Monte Carlo solver is also developed for the nongrey inhomogeneous condition and compared with the forward Monte Carlo solver. The laminar flame solver is first validated against detailed measurements of a laminar methane flame, and then applied to the target flames where only heat flux measurements are available. Good agreement with experiments is observed for all three flames, with larger discrepancy observed at downstream locations for the largest flame. Iso-contours of radiation-related scalars indicate that the laminar flames are within the optically-thin limit. Results obtained from the backward Monte Carlo solver show sensitivity to the choice of equivalent temperature that is employed for sampling wavenumbers.","PeriodicalId":413005,"journal":{"name":"Proceeding of Proceedings of the 9th International Symposium on Radiative Transfer, RAD-19","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116435211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nonlinear conduction-radiation heat transfer in the emitting, absorbing, and scattering medium is resolve by the finite volume method (FVM) method combined with discrete ordinate method (DOM) to obtain the measured signal. In the present study, two different types of reconstruction algorithms have been proposed: (1) the linear Kalman filter (KF) for the linear system, and (2) the extended Kalman filter (EKF) for the nonlinear system. All algorithms are tested in detail. All the reconstructed results show that EKF technique is robust to reconstruct the time-dependent heat flux, and internal temperature distribution in real time in coupled nonlinear conduction-radiation heat transfer systems.","PeriodicalId":413005,"journal":{"name":"Proceeding of Proceedings of the 9th International Symposium on Radiative Transfer, RAD-19","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132180679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
