exergoeconomic and enviroeconomic analyses of hybrid double slope Solar still loaded with nanofluids
Energy Conversion and Management, 2017Co-Authors: Lovedeep Sahota, G.n. TiwariAbstract:Abstract In recent times, incorporation of nanotechnology in Solar Distillation systems for potable water production is a new approach harvesting Solar thermal energy. In present manuscript, concentration of assisting nanoparticles and basin fluid (basefluid/nanofluid) mass have been optimized for hybrid Solar still operating (a) without heat exchanger (system A), and (b) with helically coiled heat exchanger (system B). Corresponding to the optimized parameters, overall thermal energy, exergy, productivity (yield), and cost analysis of the proposed hybrid systems loaded with water based nanofluids have been carried out; and found to be significantly improved by incorporating copper oxide-water based nanofluid. Moreover, on the basis of overall thermal energy and exergy, the amount of carbon dioxide mitigated per annum is found to be 14.95 tones and 3.17 tones respectively for the hybrid system (A); whereas, it is found to be 24.61 tones and 2.36 tones respectively for the hybrid system (B) incorporating copper oxide-water based nanofluid. Annual performance of the proposed hybrid systems has been compared with the conventional Solar still (system C).

Energy Conversion and Management, 2017Co-Authors: Desh Bandhu Singh, G.n. TiwariAbstract:Abstract This paper presents exergoeconomic, enviroeconomic and productivity analyses of basin type Solar stills by incorporating N identical photovoltaic thermal (PVT) compound parabolic concentrator (CPC) collectors commonly known as PVT-CPC active Solar Distillation systems. In this work, the mass flow rate and the number of collectors have been optimized and values of yearly distillate output, energy, exergy and cogeneration efficiency have been computed for the proposed Solar Distillation systems at 0.14 m water depth for the same basin area under composite climatic conditions of New Delhi. The exergoeconomic parameter, enviroeconomic parameter, productivity and cogeneration efficiency for double slope PVT-CPC active Solar Distillation system have been found to be higher by 16.22%, 21.48%, 8.56% and 5.73% respectively than obtained from a similar single slope set up at a water depth of 0.14 m for the same basin area under similar climatic condition. The proposed system can meet the potable water needs on a commercial scale and generate DC electrical power during sunshine hours.

Solar Energy, 2017Co-Authors: Desh Bandhu Singh, G.n. TiwariAbstract:Abstract In the present study, performance analysis of basin type Solar stills integrated with N identical partially covered photovoltaic thermal (PVT) compound parabolic concentrator (CPC) water collectors known as PVT-CPC active Solar Distillation systems have been carried out by incorporating the effect of water depth.

multifunctional cuo nanowire mesh for highly efficient Solar evaporation and water purification
ACS Sustainable Chemistry & Engineering, 2019Co-Authors: Yu Han, Jingjing Zhang, Fuyi Cui, Ying Zhao, Wei WangAbstract:Pure water production by Solar Distillation under no light concentration is attracting ever greater attention in the rural area with electricity limit due to its constant energy input. Meanwhile, the polluted raw water in these areas also lacks effective decontamination treatment. Rather than relying on external steps for decontamination process, photothermal materials with pollutant removal ability would have better water cleaning performance. Here, we designed a multifunctional photothermal material based on a copper mesh with abundant CuO nanowires. This CuO nanowire mesh exhibited a high Solar absorption of 93% and superhydrophilicity for water transport, contributing to a high Solar vapor efficiency of 84.4% under one-sun illumination. Besides, the CuO nanowires possessed a great catalytic ability for the degradation of contaminants in raw water. Moreover, the diffusion inhibition test showed a clear antimicrobial effect of the CuO nanowire mesh on the bacteria. Hence, the as-prepared multifunctional...

Energy Sources Part A-recovery Utilization and Environmental Effects, 2013Co-Authors: K Sampathkuma, T V Arjuna, P SenthilkumaAbstract:Solar Distillation is a promising method for clean water supply to rural communities where the quality of water is poor and sunshine is abundant. Due to a lower yield of water distilled in a passive Solar still, it is not popularly used and commercialized. Various active methods were developed to overcome this problem. A newly designed Solar still coupled with an evacuated tube collector (active Solar still) and passive Solar still for comparison purposes were fabricated and tested at Solar Energy Park, Tamilnadu College of Engineering, Coimbatore (Latitude: 11°N; Longitude: 77°E and an altitude of 409 m above sea level), Tamilnadu, India. Experiments were conducted under various meteorological conditions from June 2009 to March 2010. It has been found that maximum daily distilled water production of 7.03 and 3.225 kg obtained in active and passive Solar stills, respectively, at a water depth of 0.04 m. It has also been observed that the efficiency of an active Solar still is lower than the passive Solar ...

active Solar Distillation a detailed review
Renewable & Sustainable Energy Reviews, 2010Co-Authors: K Sampathkuma, P Pitchandi, T V Arjuna, P SenthilkumaAbstract:All over the world, access to potable water to the people are narrowing down day by day. Most of the human diseases are due to polluted or non-purified water resources. Even today, under developed countries and developing countries face a huge water scarcity because of unplanned mechanism and pollution created by manmade activities. Water purification without affecting the ecosystem is the need of the hour. In this context, many conventional and non-conventional techniques have been developed for purification of saline water. Among these, Solar Distillation proves to be both economical and eco-friendly technique particularly in rural areas. Many active Distillation systems have been developed to overcome the problem of lower distillate output in passive Solar stills. This article provides a detailed review of different studies on active Solar Distillation system over the years. Thermal modelling was done for various types of active single slope Solar Distillation system. This review would also throw light on the scope for further research and recommendations in active Solar Distillation system.
