Exact expressions for the distributions of the components of radiative flux density and the radiative energy source term in terms of wall and medium temperature distributions have been formulated for an emitting absorbing medium of constant properties bounded by black walls of a cylindrical enclosure. The accuracy of numerical solutions has been tested on an idealized enclosure for which exact analytical solution of the expressions is possible and shown to have six‐figure accuracy. The exact expressions have then been solved numerically for an enclosure problem based on data reported previously on a large scale experimental furnace. The principal feature of the data is highly non‐uniform temperature distributions which are typical of the conditions encountered in industrial furnaces. These data have been chosen because of their practical importance and the non‐availability of exact solutions for such data. The resulting exact solutions have been tabulated and are intended to serve in the future as standards for testing the accuracy of the approximate predictions produced using various three‐dimensional flux models in cylindrical configurations.

Element solution of electromagnetic problems over a wide frequency range via the Pade approximation
Kuzuoğlu, Mustafa (1999-02-12)
In electromagnetic wave propagation problems, it is usually necessary to calculate the field quantities over a wide band of frequencies. In this paper, we develop a computationally-efficient scheme, which combines the finite element method (FEM) with the Pade approximation procedure, to derive the power series expansion of the unknown solution vector in terms of the frequency. Explicit power series expressions of the matrix operator are obtained for boundary value problems that are defined, not only over bo...
Application of the boundary element method to parabolic type equations
Bozkaya, Nuray; Tezer-Sezgin, Münevver; Department of Mathematics (2010)
In this thesis, the two-dimensional initial and boundary value problems governed by unsteady partial differential equations are solved by making use of boundary element techniques. The boundary element method (BEM) with time-dependent fundamental solution is presented as an efficient procedure for the solution of diffusion, wave and convection-diffusion equations. It interpenetrates the equations in such a way that the boundary solution is advanced to all time levels, simultaneously. The solution at a requi...
Performance Evaluation of the Numerical Flux Jacobians in Flow Solution and Aerodynamic Design Optimization
Ezertas, Alper; Eyi, Sinan (2010-07-16)
A direct sparse matrix solver is utilized for the flow solution and the analytical sensitivity analysis. The effects of the accuracy of the numerical Jacobians on the accuracy of sensitivity analysis and on the performance of the Newton's method flow solver are analyzed in detail. The gradient based aerodynamic design optimization is employed to demonstrate those effects.
Calculation of the Raman frequency as a function of pressure for the phases of I, III, IV and V in cyclohexane
Yurtseven, Hasan Hamit (2014-06-05)
The Raman frequencies of the v(5) mode are calculated as a function of pressure up to 10 GPa (room temperature) for the phases I, III, IV and V of cyclohexane using the volume data from the literature by means of the isothermal mode Griineisen parameter gamma(T) of this mode.
Numerical method for conform reflection
Kushnarov, Andriy; Öktem, Hakan; Department of Scientific Computing (2010)
Conformal map has application in a lot of areas of science, e.g., fluid flow, heat conduction, solidification, electromagnetic, etc. Especially conformal map applied to elasticity theory can provide most simple and useful solution. But finding of conformal map for custom domain is not trivial problem. We used a numerical method for building a conformal map to solve torsion problem. In addition it was considered an infinite system method to solve the same problem. Results are compared.
