Predicted accuracy and computationally efficiency of Discrete Ordinates Method (DOM) and Improved Differential Approximation (IDA) were evaluated by applying both methods to cubical enclosure problems containing purely isotropically/linearly anisotropically scattering/absorbing-emitting-isotropically scattering medium and comparing their predictions with benchmark solutions available in the literature. Performances of DOM and IDA with S-8, S-10 and T-4 quadratures were assessed by comparing their predictions against benchmark solutions. DOM with S-8 and IDA with T-4 were found to provide more accurate and efficient solutions compared to other discretization schemes. However, overall comparisons reveal that DOM S-8 produces higher accuracy and computational efficiency than IDA T-4 on all test problems under consideration.

Evaluation of discrete ordinates method for radiative transfer in rectangular furnaces Selçuk, Nevin (1997-01-01) The discrete ordinates method (DOM) and discrete transfer method (DTM) were evaluated from the viewpoints of both predictive accuracy and computational economy by comparing their predictions with exact solutions available from a box-shaped enclosure problem with steep temperature gradients. Comparative testing shows that the S-4 approximation produces better accuracy in radiative energy source term than in flux density in three orders of magnitude less CPU time than that required by the DTM. The S-4 approxi...
Performance of discrete ordinates method in a gas turbine combustor simulator 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...
Efficient Computation of Green's Functions for Multilayer Media in the Context of 5G Applications Mittra, Raj; Özgün, Özlem; Li, Chao; Kuzuoğlu, Mustafa (2021-03-22) This paper presents a novel method for effective computation of Sommerfeld integrals which arise in problems involving antennas or scatterers embedded in planar multilayered media. Sommerfeld integrals that need to be computed in the evaluation of spatial-domain Green's functions are often highly oscillatory and slowly decaying. For this reason, standard numerical integration methods are not efficient for such integrals, especially at millimeter waves. The main motivation of the proposed method is to comput...
Assessment of discrete ordinates method for radiative transfer in cylindrical furnaces Selçuk, Nevin (1997-07-01) The solution accuracy of S-n or Discrete Ordinates Method (DOM) was assessed by comparing its predictions with exact solutions reported earlier on a cylindrical enclosure problem with steep temperature gradients. The enclosure has interior black walls and an absorbing-emitting medium of constant properties. Predictive accuracy was investigated for two angular quadrature schemes: 1) the S-n discrete ordinates approximation (S-2 and S-4) and 2) the modified piecewise constant angular (PCA) approximation. Comp...
Compensation of Temperature and Acceleration effects on MEMS Gyroscope Ali, Muhammad (2016-01-16) This paper shows temperature and acceleration effects on Micro-Electro-Mechanical-Systems (MEMS) gyroscope and a practical solution is presented to mitigate effect of these errors using different methods (Polynomial Curve fitting and Neural Networks). Compensation is performed on the output bias drift data acquired from different MEMS gyroscopes. Performance of compensation techniques is also presented in this study. This paper presents novelty of integrated compensation for both factors (temperature and ac...
