Accuracy of Monte Carlo method re-examined on a box-shaped furnace problem

Erturk, H

Monte Carlo method was applied to predictions of radiative heat flux density and source term of a box-shaped enclosure problem based on data reported previously on a large scale experimental furnace with steep temperature gradients typically encountered in industrial furnaces. The rectangular furnace under consideration has black interior walls and an absorbing emitting medium of constant properties. The predictive accuracy of the model was evaluated by comparing its predictions with exact numerical solutions produced previously for the same enclosure problem. The comparisons show that the model provides radiative heat flux and energy source term distributions in close agreement with the benchmark solutions.

Three flux-type models for three-dimensional radiative heat transfer were applied to the prediction of the radiative flux density and the source term of a box-shaped enclosure problem based on data reported previously on a large-scale experimental furnace with steep temperature gradients. The models, which are a six-term discrete ordinate model and two Schuster-Schwarzschild type six-flux models, were evaluated from the viewpoints of both predictive accuracy and computational economy by comparing their pred...
Monte Carlo solution of a radiative heat transfet problem in a 3-D rectangular enclosure containing absorbing, emitting and anisotropically scattering medium
Demirkaya, Gökmen; Arınç, Faruk; Department of Mechanical Engineering (2003)
In this study, the application of a Monte Carlo method (MCM) for radiative heat transfer in three-dimensional rectangular enclosures was investigated. The study covers the development of the method from simple surface exchange problems to enclosure problems containing absorbing, emitting and isotropically/anisotropically scattering medium. The accuracy of the MCM was first evaluated by applying the method to cubical enclosure problems. The first one of the cubical enclosure problems was prediction of radiat...

Elçioğlu, Elif Begüm; Okutucu Özyurt, Hanife Tuba; Mengüç, M. Pınar; Department of Mechanical Engineering (2018)
Near-field radiative transfer (NFRT) has attracted attention due to the potential of obtaining improved amount of heat transfer between media separated by distances comparable to or smaller than the dominant wavelength of emission. Such potential has been demonstrated in vacuum environments to form the basis of mainly near-field thermophotovoltaic systems and further, conversion into electricity with high system efficiency. In this thesis, an analytical analysis is performed to gain insight on nearfield rad...
Analysis of Transient Laminar Forced Convection of Nanofluids in Circular Channels
Sert, İsmail Ozan; Sezer Uzol, Nilay; Güvenç Yazıcıoğlu, Almıla; Kakaç, Sadık (2012-11-15)
In this study, forced convection heat transfer Characteristics of nanofluids are investigated by numerical analysis of incompressible transient laminar flow in a circular duct under step change in wall temperature and wall heat flux. The thermal responses of the system are obtained by solving energy equation under both transient and steady-state conditions for hydrodynamically fully developed flow. In the analyses, temperature dependent thermo-physical properties are also considered. In the numerical analys...

Kayakol, N; Selçuk, Nevin; Campbell, I; Gulder, OL (2000-03-01)
Predictive accuracy of discrete ordinates method (DOM) was assessed by applying it to the prediction of incident radiative fluxes on the walls of a gas turbine combustor simulator (GTCS) and comparing its predictions with measurements. Input data utilized for the DOM were measured gas concentration and temperature profiles and inner wall temperatures of the GTCS which is a cylindrical enclosure containing a turbulent diffusion flame of propane and air. Effects of order of approximation (S-4 and S-6) and usi...
