The main objective of the present study was to develop a new model for the solar radiation estimation in hilly areas of North India for the determination of constants ‘a’ and ‘b’ by taking only latitude and altitude of the place into consideration. In this study, new model was developed based on Angstrom-Prescott Model to estimate the monthly average daily global solar radiation only using suns...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
Incident solar radiation at the Earth's surface is the result of a complex interaction of energy between the atmosphere and the surface. Recently much progress has been made towards the creation of accurate, physically-based solar radiation formulations that can model this interaction over topographic and other surfaces (such as plant canopies) for a large range of spatial and temporal scales. ...
In this paper with the help of different empirical models we have estimated the value of monthly average global solar irradiation for Ranchi (23.3500 ̊N, 85.3300 ̊E), a tropical location. The values of monthly average global solar radiation are calculated using the regression constants in the models (both linear and quadratic) suggested by: AngstromPrescott, Rietveld, Ogleman, Akinoglu, Glover, G...
the wepp physically model is able to dynamically simulate runoff and soil erosion using physical concepts of erosion and hydraulic of overland flow science considering plant growth, residue decomposition, winter process. determination of the capability of this model in runoff and erosion estimation in different range type with investigation the effects of management were the main objectives of ...
Global solar radiation estimation is crucial for regional climate assessment and crop growth. Therefore, studies on the prediction of are emerging. With availability public data radiation, computerized models have been developed as well. These predictive play significant role in determining potentials regions suitable renewable energy generation required by engineering agricultural activities. ...
Iran has great potential in utilizing solar energy. In order to maximize the amount of absorbed solar radiation to absorber surfaces, the surfaces should be installed at a suitable angle slope to the horizon that is discussed in this article. The calculations performed in this study was done using MATLAB software. In this study, radiation received on the ground in 31 provincial capitals of the ...
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 ...
Climatic conditions have a significant impact on the energy consumption of buildings. Also check the angle of the solar radiation on buildings and controlling the amount of heat absorbed on building shell during the year have significant impact on building energy efficiency. The aim of this study was to investigate the effect of orientation of the building on the energy consumption and to this...
