In this study, exergy analysis of a novel desalination system is presented and discussed. The water desalination is carried out using combined humidification–dehumidification and reverse osmosis technologies. Six system performance parameters are examined: overall exergetic efficiency,...

Integrating solar thermal technologies with gas turbine cogeneration plants reduces fuel consumption and consequently results in a considerable reduction in gas emissions. These technologies are expected to play an important role in solving the global environmental and energy problems. The...

The gross domestic product (GDP) measures the value of goods and services produced in a country in one year. There is a close relationship between the GDP and energy supply (and consumption). This relationship is a good indication of the level of economic development of a country. The GDP per...

There is an intimate connection between energy, the environment and sustainable development. A society seeking sustainable development ideally must utilize only energy resources which cause no environmental impact (e.g. which release no emissions to the environment). However, since all energy...

Fourier and Reynolds correlations are presented for determining the values of thermal parameters defined in terms of the half cooling times and seven-eighths cooling times for spheres and cylinders being cooled in air or water flows. In this respect, an experimental, modeling and...

In this study, a methodology to determine cooling-process parameters (i.e. lag factor, cooling coefficient, half cooling time and seven-eighths cooling time) and an analytical model for determining film conductances during cooling of spherical food products were proposed. Temperature...

This paper presents a new mathematical model for determining thermal diffusivities of very common solid geometrical objects such as an infinite slab, infinite cylinder, or sphere cooled in a medium. In practice the model will be implemented by using the center temperature measurements of these...
