Solar Chimney Cycle Analysis With System Loss and Solar Collector Performance

A B S T R A C TIn this article, a new combination of solar chimney and Humidification-Dehumidification desalination process is introduced. In this system, the air is humidified by injection of water drops into the air flow. Then, the partial of vapors contained in the air is condensed on the outer surface of the cold water tubes. Two mathematical models have been developed for a one-dimensional flow in the solo solar chimney and the integrated system. The performance of the integrated system including power and potable water production is estimated and the results are discussed. Furthermore, it has been demonstrated that increasing in the temperature and mass flow rate of humidifier inlet water would improve the performance of the integrated system. It is found that the increase in water production would cause the decrease in power output. Also, to produce more fresh water, the number of dehumidifier tubes should be increased.

The paper presents a new design for solar chimney plants to be erected on mountainous terrain. The objective is to exploit the height of nearby mountains to replace the conventional vertical chimney by a duct built over the steep side of the mountain. The concept is evaluated here employing a computational model involving three-dimensional governing equations, describing mass, momentum and energy balances, in addition to transport of two turbulence quantities. A typical application is demonstrated for a 45 0 sloped mountain. The concept is shown to be plausible and offers many advantages over conventional chimney designs.

“…Gannon and Backstrom [76] developed an ideal air-standard cycle analysis to calculate all the thermodynamic variables depending on the chimney height, wall friction, additional losses, internal drag and area change. The developed analytical model showed good agreement with the experimental results of the small-scale plant built in Manzanares allowing it to be used reliably in the prediction of the output of a full-scale plant.…”

The increased utilization of solar energy has gained the attention of researchers to develop the solar chimney (SC) technology in recent years. Many studies have been conducted in this aear both experimentally and theoretically, whereas experimental studies are mainly focused on small-scale systems. This work provides a comprehensive and updated review that include most of the experimental studies, analytical and simulation works, the solar chimney applications, hybrid systems and geographical case studies based on extended references, citation of the updated works and the specified way of looking at different sections. The technological gaps in differnet sections are identified and a summary of suggestions is given for the future work, including more experimental works on the large-scale systems, and CFD analyses for optimization between the geometrical parameters and the output power. More studies on new applications of solar chimney technology including hybrid systems are also recommended.
