Heavy machinery operating in outdoor environments is exposed to both solar radiation and intensive load-bearing during operation. The long operating life of these machines and their components is enabled by the greases used in their bearings. The thermal properties of these greases play a crucial role in dissipating both the heat generated by frict...

Bu çalışma, kare kapalı kutu içindeki ısıtılmış eğimli eliptik silindirin doğal taşınımla ısı geçişini inceleyebilmek için iki boyutlu sayısal olarak analiz edilmiştir. Çalışmada kare kapalı kutunun yüzeyleri soğuk, eliptik silindir ise ortamın tek ısı kaynağıdır. Analiz yapılırken eliptik silindir için üç farklı eğim açısı (θ=0°, 45°, 90°), elipti...

Unsteady laminar mixed (forced and free) convection heat transfer and fluid flow over long horizontal equilateral triangular cylinder subjected to upward cross flow are investigated numerically. The computation model is a two-dimensional unconfined rectangular domain with an aspect ratio of 1.4. A second order upwind scheme was used for differencin...

Three dimensional combined natural convection and thermal radiation in an inclined cubic enclosure with pins attached to the active wall is investigated numerically. The vertical opposing walls are heated and cooled while the other walls are assumed to be adiabatic. The governing flow, momentum equations and the radiative transfer are solved using...
Article
Alternative synthetic kernel (ASKN) approximation, just as the standard SKN method, is derived from the radiative integral transfer equations in full 3D generality. The direct and diffuse terms of thermal radiation appear explicitly in the radiative integral transfer equations as surface and volume integrals, respectively. In standard SKN method, t...

In this study, laminar natural convection heat transfer in 3D rectangular air filled enclosures, with pins attached to the active wall, is studied numerically. Two cases of rectangular enclosures are considered: H/L = 1 and H/L = 2. The enclosure is heated from a lateral wall and is cooled from the opposite lateral wall while the other walls of the...
