The following quadratic equation was previously developed to estimate the monthly average solar radiation in any place in Turkey: = a + b tc {sup 2} where is the ratio of the monthly averages of the bright sunshine to the length of the day, a and b are constants that depend on location. The measured solar radiation and bright sunshine data from two stations, totalling 1842 days, were used to evaluate the constants. In 1982 the State Meteorological Office of Turkey started solar radiation measurements in six climatologically different regions with Epply precision pyranometers. The duration of sunshine has also been recorded in the same locations with Campbell-Stokes type instruments since 1966. However, the solar radiation measurement program was later abandoned due to systematic measurement errors observed in the instruments. We have checked these data and have taken only those from reliable months. In this study, we have used the data to improve the value of regression coefficients of the equation.

ANALYSIS OF THE INTEGRATED INTENSITY OF THE CENTRAL PEAKS CALCULATED AS A FUNCTION OF TEMPERATURE IN THE FERROELECTRIC PHASE OF LITHIUM TANTALATE Kiraci, Ali; Yurtseven, Hasan Hamit (National Library of Serbia, 2018-01-01) The integrated intensity of the central peak is calculated as a function of temperature in the ferroelectric phase (T < T-C) of nearly stoichiometric LiTaO3. This calculation is performed using the temperature dependence of the order parameter obtained from the mean field theory at temperatures lower than the transition temperature T-C (T-C = 963 K) of this crystal. The calculated values of the order parameter (squared) are fitted to the integrated intensity of the central peaks as observed from the Raman a...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01) The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...
Computation of instantaneous fuel consumption for the determination of combustion efficiency with special reference to coal briquette size Altun, Naci Emre; Bagci, AS (Informa UK Limited, 2006-04-01) This study comprises of the computation of instantaneous fuel consumptions as a straight means for the interpretation of combustion-related characteristics of coal. The model relies on the determination of the extent of combustion by the calculated fuel combustion amounts at specific instants in order to examine the oxidation behavior and possible influences governed by any variable of interest. In this context, coal briquettes prepared by varying dimensions with and without a volume constraint were evaluat...
The potential and economic viability of solar photovoltaic power in Ghana Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (Informa UK Limited, 2016-01-01) In this study, the potentiality and economic viability of solar photovoltaic (PV) in Ghana was assessed using RETScreen software. 5 MW of grid-connected solar PV power system using SunPower SPR-320E-WHT-D PV module can be harnessed from Navrongo, Bawku, Wa, Tema, Bolgatanga, Axim, Salaga, Kintampo, Kete Krachi, Tamale, Hohoe, Koforidua, Ejura, Takoradi, Bole, Sunyani, Bibiani, Cape coast, Prestea, and Akuse, which requires US$17,752,179 of investment capital and 25,313 m(2) of land for PV installation. The ...
MAPS FOR AVERAGE BRIGHT SUNSHINE HOURS IN TURKEY TASDEMIROGLU, E; Sever, Ramazan (Elsevier BV, 1991-01-01) This paper provides the isopleth maps for the monthly average daily bright sunshine hours in Turkey. The data from 50 stations are elaborated. The maps are generated by the aid of a developed computer program.
