Multigroup Correlated-k Distribution Method for Nonequilibrium Atomic Radiation
Accurate and efficient modeling of shock-layer radiative heat loads is critical for many spacecraft designs. A correlated-k distribution method has been developed for the most important atomic species (N and O), which provides great accuracy with high numerical efficiency for the evaluation of radiative transfer in a hot plasma. Challenges posed by typical nonequilibrium gas conditions and extr...
متن کاملMultiscale Part-Spectrum k-Distribution Database for Atomic Radiation in Hypersonic Nonequilibrium Flows
An accurate and compact part-spectrum k-distribution database has been developed for the two most important radiating species N and O encountered in hypersonic nonequilibrium flows. The database allows users to calculate the desired full-spectrum k-distributions through look-up and interpolation, providing an efficient means to perform radiative transfer calculations. A detailed methodology of ...
متن کاملA Narrow Band-Based Multiscale Multigroup Full-Spectrum k-Distribution Method for Radiative Transfer in Nonhomogeneous Gas-Soot Mixtures
The full-spectrum k-distribution (FSK) approach has become a promising method for radiative heat transfer calculations in strongly nongray participating media, due to its ability to achieve high accuracy at a tiny fraction of the line-by-line (LBL) computational cost. However, inhomogeneities in temperature, total pressure, and component mole fractions severely challenge the accuracy of the FSK...
متن کاملA Radiation Algorithm with Correlated-k Distribution. Part I: Local Thermal Equilibrium
A new radiation scheme is proposed that uses the correlated-k distribution (CKD) method. The definition of the k-distribution function, the transformation between frequency space and k space, and the upper limit of the absorption coefficient in cumulative probability space (CPS) are discussed. The corresponding relation between each interval in CPS and the heating rate profile provides a method...
متن کاملA new method for ideal dose distribution of two adjacent fields for external beam radiation therapy
Abstract Background: Adjacent treatment fields are commonly used in external beam radiation therapy, such as mantle and inverted-Y fields for the treatment of Hodgkin’s disease and craniospinal fields used in the treatment of medulloblastoma and head and neck tumors when the lateral neck fields are placed adjacent to the anterior supraclavicular field. In each of these situations, there is a p...
