How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
In this study condensation heat transfer on a cold inclined circular cylinder due to natural convection for various conditions is investigated experimentally. The cylinder is placed in an isolated test room to permit pure natural circulation of ambient air. Ambient temperature and humidity of the test room are controlled by a refrigeration cycle an...
In the present paper, the practical efficiency of using alumina-water nanofluid was evaluated numerically by the method of entropy generation; pumping power and tube wall temperature were analyzed. Laminar forced convection by water-based nanofluid flow through a uniformly heated circular tube is considered. A single?phase fluid approach is adopted...
Energy consumption and carbon emissions in Iran have risen rapidly in recent years which is not acceptable regarding environmental regulations. Government officials have been trying to resolve this problem, but so far there has been less success. Exergy analysis method is a powerful tool, which has been successfully used for estimating energy utili...
Split-type air-conditioners used in residential or office buildings often have the outdoor condensing units installed at the sidewalls or on the roofs. Installation distance from the supporting wall for the first group and the height of installation for the second group are two factors that affect the condenser efficiency. In this study, a CFD code...
