Numerical analysis of laminar natural convection in isosceles triangular enclosures for cold base and hot inclined walls
چکیده انگلیسی

In this work, a numerical analysis of laminar natural convection in an enclosure of isosceles triangular cross-section has been performed for cold base and hot inclined walls. Base angles varying from 15° to 75° have been used for different Rayleigh numbers ranging from 103 to 105. Effects of Rayleigh number and aspect ratio on the flow field and heat transfer are analyzed. The streamline patterns and temperature distributions are presented. It is observed that the enclosures with a low aspect ratio have higher heat transfer rates from the bottom surface of the triangular enclosure.
