Parabolic Collector

From geographic data around the planet is covered around 70% with water, but out of total, only around 2% is of fresh water, and out of total fresh water, about 1.6% is not used because it is located in polar ice caps and glaciers. So total of the earth’s water, 98% is saltwater, 1.6% is in polar ice caps and glaciers, and 0.4% is drinkable water, which is available from underground wells or rivers. The survey shows that around 1 billion people, or 14.7% of the total earth’s population, still do not have pure safe drinkable water. So here an effort is made to design a water distillation system with use of the solar parabolic trough that can purify water from any source of water and convert it in to drinkable form. A solar parabolic trough collector is used to convert water into steam and later condense the steam to get pure water.

Parabolic Collector

Solar energy is available in abundant quantity which can be utilized for thermal and power generation applications. The maximum solar energy extraction for application is challenging. This review focuses on the performance enhancement of parabolic trough collector. Heat transfer through absorber tube, various nanofluids with concentration is stated. Thermal efficiency increases due to the use of parabolic collector with booster reflector and glass cover over the system performance. The complex 3D analysis (ANSYS) gives accurate distribution of heat flux over the absorber tube.

Health And Well Being

Water is one of necessity of life without which it is not possible for life to sustain. Approximately 71% part of the earth is enclosed with water in which 97% seawater, 2% polar ice caps, and 1% is fresh water. Water quality is an indicator of environmental health and well being of society. The environment nearby river area are very productive, beside this they also have economically values for fisheries, tourism, and recreational activities (Donde and Patil, 2018).  In India, approximately 1000 rivers are present which are source of livelihood for large number of population.

Water desalination is receiving increasing attention due to water scarcity in many places in the world. Although two third of the earth is covered with water, most of this water is salty (97.5%) and therefore not suitable for human, animal or plant needs. Furthermore, most of the fresh water available throughout the work is not accessible such as icebergs and some deep ground water. Water uneven distribution throughout the world creates another problem of water scarcities in arid places. Africa and Middle East are having the smallest share of natural, pure water resources. Fortunately, these areas of arid climate and low fresh water are rich in the most significant renewable energy source, solar energy. In this chapter, the potential of the utilization of renewable energy sources is discussed. Several desalination techniques that can be powered by renewable energy are discussed. Those techniques include the non-conventional ones such as the solar stills, humidification dehumidification desalination and membrane distillation. What is common within all of these techniques is the relatively low temperatures needed to operate the plants (around 80 °C) that can be afforded easily using solar collectors for heating water (and sometimes air). Several layouts of humidification dehumidification systems and membrane distillation system are also discussed in details taking into consideration the improvement of performance due to energy recovery systems and the recent trends of such technologies. Although the solar energy is basically free source of energy, how good this energy is utilized in operating the desalination systems is considered in the gain output ratio (GOR) that allows for comparison of different systems comparison and shows the room for improvement.

Abstract Concentrated solar power technologies have been studied in recent years as a potential solution for energy production industry , however this kind of systems face different challenges in order to increase thermal performance and efficiency. This paper presents the results of a thermal analysis on a parabolic trough collector with different receivers internal fins configurations, systems were studied in CFD Solidworks® flow simulation software and compared with a traditional parabolic collector with cylindrical receiver. Results shows that the lowest thermal performance was achieved with a cylindrical pipe, instead fractal fins receiver with 5 internal fins achieves a temperature increase of 27% and the best pipe configuration was fractal Descartes with 12 internal pipes which e the cylindrical temperature in 29%.

There is an ever increasing need to provide clean and portable drinking water in developing countries because of the poor quality of water, which causes various water borne diseases killing millions of infants and elderly people every year. There have been a lot of recent developments in the field of solar enabled water distillation where pure water is being generated. But a majority of the system use some type of external energy source for the system to run on which might make it efficient but can cause dependence on energy sources. The power of the Sun can be effectively harnessed and used as heat and light source for efficient steam generation. One of the challenges is to develop a low cost system which can perform at par with the best and extravagant systems. This paper investigates the performance of the solar distillation system when activated carbon nanoparticles are used along with brine and other sources of impure water so as to obtain clean water. The activated carbon nanoparticle which are an efficient and cheap mode of water purification enhanced the productivity of the system by 190% when compared to saline water due to its steam generation properties. A solar simulator of 1KWm2 was used to simulate the sun. Various parameters like the variation of air flow on condensation rate, height of fluid on vapor production rate and the temperature variation of the system are evaluated. Parametric studies of the effect of water quality and salinity were performed. It was determined that the optimum output rate of distilled water was 240 grams (6000gday.m2) was determined by the system from the parametric studies and the system is feasible and cost effective to be used in real world application. All of these standout features make the system a low cost option which can tackle the clean water dilemma in developing countries.

The clean and pure drinking water is important in today's life but current water sources are usually brackish with bacteria that cannot be used for drinking. About 78% of water available in the sea is salty, 21% of water is brackish, and only 1% of water is fresh. Distillation is one of the feasible processes applied to water purification, and it requires the energy inputs, such as solar radiation. Water is evaporated in this distillation process and water vapor can be separated and condensed to pure water. Now, with the change from conventional fuels to renewable and environment friendly fuels sources, the modern technology allows to use the abundant energy from the sun. It is better to use solar energy to process the water desalination since it is more economical than the use of conventional energies. The main focus of this paper is applying computer-aided modeling and simulation to design a less complex solar water distillation system. The prototype of this solar still system is also built to verify its feasibility, functionality, and reliability. The computational simulation and prototype testing show the reliability and proper functionality of this solar water distillation system.
