Modeling of 3-D non-gray gases radiation by coupling the finite volume method with weighted sum of gray gases model
(International Journal of Heat and Mass Transfer, 2004)
A new model and code for radiative heat transfer based on the numerical solution of the radiative transfer equation by finite volume method in 3-D Cartesian coordinates coupled with weighted sum of gray gases model (WSGGM) ...
Analytical solution of transient heat conduction in a two-layer anisotropic cylindrical slab excited superficially by a short laser pulse
(International Journal of Heat and Mass Transfer, 2004)
This paper presents an exact analytical solution of 2D transient temperature, caused by a non-periodical pulse heating of a cylindrical two-layer slab. The corresponding partial differential equations are solved step-by-step, ...
A two-dimensional model of the kettle reboiler shell side thermal-hydraulics
(International Journal of Heat and Mass Transfer, 2006)
A two-dimensional two-fluid numerical model is developed for the prediction of two-phase flow thermal-hydraulics on the shell side of the kettle reboiler. The two-phase flow around tubes in the bundle is modeled with the ...
