RISRadiative Heat Transfer in Turbulent Combustion 2021 Max Jakob Memorial Award Paper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In many important combustion applications, heat transfer is dominated by thermal radiation from combustion gases and soot. Thermal radiation from combustion gases is extremely complicated, and accurate and efficient ...
The Treatment of Nongray Properties in Radiative Heat Transfer: From Past to Present
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Radiative heat transfer in hightemperature participating media displays very strong spectral, or “nongray,†behavior, which is both very difficult to characterize and to evaluate. This has led to very gradual development ...
Advanced Differential Approximation Formulation of the PN Method for Radiative Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The spherical harmonics (PN) method, especially its lowest order, i.e., the P1 or differential approximation, enjoys great popularity because of its relative simplicity and compatibility with standard models for the solution ...
A Hybrid Wavenumber Selection Scheme for Line By Line Photon Monte Carlo Simulations in High Temperature Gases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, it has become possible to conduct linebyline (LBL) accurate radiative heat transfer calculations in spectrally highly nongray combustion systems using the Monte Carlo method. LBL accuracy, in principle, adds ...
Line-by-Line Random-Number Database for Monte Carlo Simulations of Radiation in Combustion System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With today's computational capabilities, it has become possible to conduct line-by-line (LBL) accurate radiative heat transfer calculations in spectrally highly nongray combustion systems using the Monte Carlo method. In ...
Comparisons of Radiative Heat Transfer Calculations in a Jet Diffusion Flame Using Spherical Harmonics and k Distributions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new nongray radiation modeling library for combustion gases has been implemented in OpenFOAM. The spectral models for single species include gray, correlation tables and full spectrum kdistributions (FSK) assembled from ...
Spectral Photon Monte Carlo With Energy Splitting Across Phases for Gas–Particle Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In multiphase modeling of fluidized beds, pulverized coal combustors, spray combustors, etc., where different temperatures for gas and solid phases are considered, the governing equations result in separate energy equations ...
Monte Carlo Simulation for Radiative Transfer in a High-Pressure Industrial Gas Turbine Combustion Chamber
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Radiative heat transfer is studied numerically for reacting swirling flow in an industrial gas turbine burner operating at a pressure of 15 bar. The reacting field characteristics are computed by Reynolds-averaged Navier–Stokes ...
Implementation of High Order Spherical Harmonics Methods for Radiative Heat Transfer on openfoam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general formulation of the spherical harmonics (PN) methods was developed recently to expand the method to high orders of PN. The set of N(N + 1)/2 threedimensional secondorder elliptic PDEs formulation and their ...
Full-Spectrum Correlated-k Distribution for Shortwave Atmospheric Radiative Transfer
Publisher: American Meteorological Society
Abstract: The full-spectrum correlated k-distribution (FSCK) method, originally developed for applications in combustion systems, is adapted for use in shortwave atmospheric radiative transfer. By weighting k distributions by the ...
