The efficiency with which energy and raw materials are used within the 7process industries depends strongly on the way in which resources are distributed within a manufacturing site. Most sites or processes contain several sources or sinks of the resource. For example, a chemical plant will have...

This paper presents a steady-state and transient theoretical exergy analysis of a solar still, focused on the exergy destruction in the components of the still: collector plate, brine and glass cover. The analytical approach states an energy balance for each component resulting in three coupled...

In this study, efficiency evaluation for Keban hydropower plant (KHPP), located in Elazig–Turkey, was performed both experimentally and numerically by using thermodynamic analysis. Turbine efficiency was measured with direct method by measuring temperature of turbine inlet and outlet....

Ethanol is one of the most important renewable biofuels contributing to the reduction of negative environmental impacts generated by the worldwide utilization of fossil fuels, and the presence of metal ions in fuel ethanol has significant effect on the performance and the quality of fuel. In the...

The last two decades have offered a dramatic rise in the use of digital technologies such as wireless sensor networks that require small isolated power supplies. Energy harvesting, a method to gather energy from ambient sources including sunlight, vibrations, heat, etc., has provided some...
