In rapidly developing urban areas of emerging countries, increased water demand has led to enormous groundwater withdrawal, calling out for sustainable groundwater management. We suggest implementing a sustainable pumping rate concept based on numerical modeling of the managed aquifer....

The government of Egypt has decided to construct a new barrage with hydropower facilities, 3.5 km downstream of the existing old one. The water levels in the head pond for the new barrage will be continuously maintained at a level with approximately 0.5 m higher than water level in the head pond...

The lower sub-aquifers of the Mediterranean coastal aquifer of Israel, at the Palmahim area, are hypothesized to be laterally blocked to connection with the sea, and thus to seawater intrusion. This is mostly due to the detection of fresh water bodies at these sub-aquifers. This study examine...

Solar ponds are low-cost, large-scale solar collectors with integrated storage that can be used as an energy source in many thermal systems. Experimental solar pond investigations at smaller scales have proven to be useful when trying to understand how different factors affect the pond’s...

In the present work an investigation of the potential use of waste derived fuel gas in molten carbonate fuel cell (MCFC) systems is performed. A simple numerical model of a MCFC is developed following a “system-level” approach that allows to investigate the impact of MCFC performance with...

This paper presents investigation on the use of solar chimney (SC) in high-rise building. To this end, two small scale models of a three storey building were built. The floor dimensions of each storey are 1.2×2×1m. Solar chimneys were integrated into the south-faced walls of one unit whereas...

Solar distillation literature reports a generalized use of stills with single and double slope condensing covers, where modeling equations describe a solution approach that considers the condenser as a single element. The solution for a double slope still analysis is generally forced to the case...

Because of economic growth and a strong increase in global energy demand the demand for fossil fuels and therefore also greenhouse gas emissions are increasing, although climate policy should lead to the opposite effect. The coal market is of special relevance as coal is available in many...

A geodatabase of tidal constituents is developed to present the regional assessment of tidal stream power resource in the USA. Tidal currents are numerically modeled with the Regional Ocean Modeling System (ROMS) and calibrated with the available measurements of tidal current speeds and water...

A theoretical model of binary alloy melting and solidification induced by pulsed-laser irradiation is formulated using the mass and internal energy balances in the liquid and solid phases. The interface between the solid and liquid phases is modeled as a discontinuity surface where the mass and...
