Effects of wall-located heat barrier on conjugate conduction/natural- convection heat transfer and fluid flow in enclosures
Hakyemez, Erinç; Mobedi, Moghtada; Öztop, Hakan Fehmi (Taylor & Francis, 2008-01)The effects of a heat barrier, located in the ceiling wall of an enclosure, on conjugate conduction/natural convection are investigated numerically. The vertical walls of the enclosure are differentially heated and the ... -
Heat transfer reduction due to a ceiling-mounted barrier in an enclosure with natural convection
Gediz İliş, Gamze; Mobedi, Moghtada; Öztop, Hakan Fehmi (Taylor & Francis, 2011)Effects of a ceiling-mounted barrier on natural convection heat transfer in a square cavity with differentially heated wall are numerically investigated. A limit case, in which the partition has small thickness and low ... -
A heatline analysis of natural convection in a square inclined enclosure filled with a CuO nanofluid under non-uniform wall heating condition
Öztop, Hakan Fehmi; Mobedi, Moghtada; Abu-Nada, Eiyad; Pop, Ioan (Elsevier, 2012-09)Heatline visualization technique is used to understand heat transport path in an inclined non-uniformly heated enclosure filled with water based CuO nanofluid. The cavity has square cross-section and it is non-uniformly ... -
Using of Bejan's heatline technique for analysis of natural convection in a divided cavity with differentially changing conductive partition
Koca, Ahmet; Öztop, Hakan Fehmi; Varol, Yasin; Mobedi, Moghtada (Taylor & Francis, 2013-08)The issue of laminar natural convection and conduction in enclosures divided by a partition with different thicknesses is investigated numerically. The partition is accepted as conductive at different thermal conductivity ... -
Visualization of heat flow using Bejan's heatline due to natural convection of water near 4 °C in thick walled porous cavity
Varol, Yasin; Öztop, Hakan Fehmi; Mobedi, Moghtada; Pop, Ioan (Elsevier, 2010-04)A numerical study on natural convection heat transfer of cold water near 4 °C in a thick bottom walled cavity filled with a porous medium has been performed. It is assumed that the cavity is isothermally heated from the ... -
Visualization of heat transport using dimensionless heatfunction for natural convection and conduction in an enclosure with thick solid ceiling
Mobedi, Moghtada; Öztop, Hakan Fehmi (Elsevier, 2008-11)A conjugate conduction-(natural)convection problem is numerically studied in order to present the application of dimensionless heatfunction for entire computational domain including solid and fluid regions in an enclosure ... -
Visualization of natural convection heat transport using heatline method in porous non-isothermally heated triangular cavity
Varol, Yasin; Öztop, Hakan Fehmi; Mobedi, Moghtada; Pop, Ioan (Elsevier, 2008-10)Natural convection heat transfer in a porous media filled and non-isothermally heated from the bottom wall of triangular enclosure is analyzed using finite difference technique. Darcy law was used to write equations of ...
