The Savonius wind turbine appears to be particularly promising for low power applications, such as those in urban areas, and it can take advantage of a simple, reliable and cost-effective construction. Anyway, the Savonius wind turbine suffers from poor performance, when compared with other wind...

Domestic hot water tanks represent a significant potential demand side management asset within energy systems. To operate effectively as energy storage devices, it is crucial that a stratified temperature distribution is maintained during operation; this paper details experimental and numerical...

Recent built low energy school buildings have adopted a novel heat recovery heat pump and classroom ventilation system. School building energy conservation performance and classroom air quality enhancement will be simultaneously investigated in the present work. Heat recovery efficiency of the...

Wind turbines operate under various wind conditions in which turbulence virtually always exists. Therefore, unsteady wind turbine simulation methods to estimate wind loading in turbulent inflow conditions are very important for developing optimally designed wind turbines. Several methods have...

The objective of the present paper is to study the oil flows from damaged submarine pipelines with different leak sizes. CFD (computational fluid dynamic) simulations with FLUENT software are carried out to investigate the process of oil spill from submarine pipeline to free surface. Effects of...
