The numerical investigation of computing the rate of radiated solar-energy requires equations as a function of solar-time according to the radiation angle of the sun (β) in the latitude 37°N and the shape. This paper implements the Lagrange interpolation to obtain the equations of normal diagram of elements based on data obtained from surveying. Also the method of Hann-window equation ...

Solar energy is receiving lots of attention because it is one of the cleanest, cheapest and most available energies in the world.but solar radiation in different parts is changing, thus, identifying appropriate locations for implementation of solar energy is necessary. Accordingly the aim of this study was to analyze the potential of solar radiation and land surface temperature on the Loot dese...
In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, the application of active solar systems for the dining hall is evaluated. The impact of solar systems and energy management designed for this hall on energy consumption and environment was investigated.This study measures the electricity and thermal energy consumption of the dining hall , p...
In the present study, investigated an energy production system using three types of renewable energy: solar, wind and ocean thermal energy with climatic conditions and close to areas with high potential for the OTEC system, Has a good position in terms of wind speed and solar radiation, used them as energy sources. The proposed system is designed and evaluated based on the total daily electrici...
nowadays two important discussions in academic parties all over the world are energy crisis and environment crisis. one of the strategies to deal with these crisises is using clean, renewable and domestic energy sources. one of the best renewable energies that can be used in different scales is solar energy. in iran which is considered among the greatest countries that receive huge amount of so...

Regarding to the increase of cost and consumption of the nonrenewable energies such as natural gas and electricity, using renewable energies such as solar energy reduces the consumption of nonrenewable energies. In this research, at first, a regenerative organic Rankine cycle with flat plate solar collector as energy source is simulated and the effects of different parameters such as turbine in...
Solar energy is the most unique renewable energy source in the world and is the main source of all energy on Earth. Solar energy can be converted into other forms of energy directly and indirectly. In general, the energy given off by the sun about 3. 8 two 1023 kW per second. In the present study, the potential of solar energy in the province of surveillance data 9 synoptic stations located in ...
titania nanotubes (tnt) prepared by anodization of ti foils were used for water splitting in a standalone cell. the concentration polarization between the anode side (1m naoh) and cathode side (0.5 m h2so4) ensured that the water splitting reaction could take place with no external bias and separate h2 and o2 evolution could be achieved. the destruction of tnt structures under 365 nm uv irradia...
