A radiation code based on the method of fines (MOL) solution of the discrete ordinates method (DOM) for transient three-dimensional radiative heat transfer in rectangular enclosures for use in conjunction with a computational fluid dynamics (CFD) code based on the same approach,vas developed. Assessment of the predictive accuracy of the code by benchmarking its steady-state solutions against exact solutions on one- and three-dimensional test problems shows that the MOL solution of the DOM provides accurate and computationally efficient solutions for radiative heat fluxes and source terms and call be used with confidence in conjunction with CFD codes for transient problems.

The method of lines solution of discrete ordinates method for radiative heat transfer in cylindrical enclosures Harmandar, S; Selçuk, Nevin (2004-04-01) A radiation code based on method of lines solution of discrete ordinates method for radiative heat transfer in axisymmetric cylindrical enclosures containing absorbing-emitting medium was developed and tested for predictive accuracy by applying it to (i) test problems with black and grey walls (ii) a gas turbine combustor simulator enclosing a non-homogeneous absorbing-emitting medium and benchmarking its steady-state predictions against exact solutions and measurements. Comparisons show that it provides ac...
The method of lines solution of discrete ordinates method for non-grey media Cayan, Fatma Nihan; Selçuk, Nevin (2007-03-01) A radiation code based on method of lines (MOL) solution of discrete ordinates method (DOM) for radiative heat transfer in non-grey absorbing-emitting media was developed by incorporation of a gas spectral radiative property model, namely wide band correlated-k (WBCK) model, which is compatible with MOL solution of DOM. Predictive accuracy of the code was evaluated by applying it to 1-D parallel plate and 2-D axisymmetric cylindrical enclosure problems containing absorbing-emitting medium and benchmarking i...
The method of lines solution of discrete ordinates method for Nongray media experimental Çayan, Fatma Nihan; Selçuk, Nevin; Department of Chemical Engineering (2006) A radiation code based on method of lines (MOL) solution of discrete ordinates method (DOM) for the prediction of radiative heat transfer in nongray absorbing-emitting media was developed by incorporation of two different gas spectral radiative property models, namely wide band correlated-k (WBCK) and spectral line-based weighted sum of gray gases (SLW) models. Predictive accuracy and computational efficiency of the developed code were assessed by applying it to the predictions of source term distributions ...
The method of lines solution of the discrete ordinates method for radiative heat transfer in enclosures containing scattering media Selçuk, Nevin; Ayranci, I (2003-02-01) A radiation code based on the method of lines (MOL) solution of the discrete ordinates method (DOM) for three-dimensional radiative heat transfer in rectangular enclosures containing gray, absorbing, emitting, isotropically and anisotropically scattering media was developed. Predictive accuracy of the code was evaluated by applying the code to 1-D and 3-,D problems containing scattering media and benchmarking its predictions against exact solutions, the zone method, and Monte Carlo solutions. Favorable comp...
A 3-D radiation model for non-grey gases Selçuk, Nevin (2009-02-01) A three-dimensional radiation code based on method of lines (MOL) solution of discrete ordinates method (DOM) coupled with spectral line-based weighted sum of grey gases (SLW) model for radiative heat transfer in non-grey absorbing-emitting media for use in conjunction with a computational fluid dynamics (CFD) code based on the same approach was developed. The code was applied to three test problems: two containing isothermal homogenous/non-homogenous water vapor and one non-isothermal water vapor/carbon di...
