In this paper, a new design of inclined solar still with steppe absorber plate, slope surfaces and baffles were proposed, fabricated, tested modeled using ANSYS FLUENT software, in order to develop the simple cheapest type desalination. The simulation has been carried out validated experimental data for climate conditions Rabat-Morocco (34°47’N) obtained from our existing prototype. It found th...

Pure and fresh water is being scarce day by day. Although Bangladesh is a riverine country, pure drinking potable water is not a cheap commodity. Most of the people in the cities boil water to drink, and people of the villages take tube-well’s water directly, which might have high amount of heavy metal like arsenic. Solar still is a cheap and very useful renewable technology, which can be used ...

BACKGROUND An experimental work was reported to estimate the increase in distillate yield for a compound parabolic concentrator-concentric tubular solar still (CPC-CTSS). The CPC dramatically increases the heating of the saline water. A novel idea was proposed to study the characteristic features of CPC for desalination to produce a large quantity of distillate yield. A rectangular basin of dim...

This paper reports the use of a mathematical model to predict the productivity of a simple solar still under different climatic, design and operational parameters in Oman. The shallow water basin, 23 cover tilt angle, 0.1 m insulation thickness and asphalt coating of the solar still were found to be the optimum design parameters that produced an average annual solar still yield of 4.15 kg/m day...

In this communication an attempt has been made to find out distribution of solar radiation, using the concept of solar fraction inside a conventional (single slope) solar still by using AUTOCAD 2000 for a given solar azimuth and altitude angle and latitude, longitude of the place. Further the experimental validation of the model developed earlier has been carried out for design and climatic par...

Abstract: Perovskite solar cells have become an attractive subject in the solar energydevice area. During ten years of development, the energy conversion efficiency has beenimproved from 2.2% to more than 22%, and it still has a very good potential for furtherenhancement. In this paper, a numerical model of the perovskite solar cell with thestructure of glass/ FTO/ TiO2/...

Background: Although cryotherapy is still the first-line therapy for solar lentigines, due to side effects such as post-inflammatory hyperpigmentation (PIH), especially in patients with darker skin types, pigment specific lasers should be considered as initial treatment. The aim of this study was to evaluate the efficacy and safety of cryotherapy in comparison with 595-nm pulsed dye laser (PDL)...
