Peninsular Spain. Weather data are the key drivers of hydrological modelling. However, available weather can present gaps in sequences and often limited their spatial coverage for use such models as Soil Water Assessment Tool (SWAT). To overcome this limitation, SWAT includes a generator algorithm that complete based on long-term statistics. This work presents newly developed statistics dataset...

Turbulence analysis of flow inside a hydrocyclone is carried out using commercially available CFD software ANSYS-CFX (release 11.0). Commercial CFD software(s) and their turbulence models have come a long way in accurately predicting the flow inside a hydrocyclone, both at the mean as well as at the turbulence level. Previous studies have shown, the more accurate the turbulence prediction is, t...

A new type of single-phase stand-alone induction generator using a three-phase induction machine and a single-phase voltage-source PWM inverter is introduced. The generator scheme is capable of producing constant load frequency with a very well regulated output voltage. A small lead acid battery and a single-phase full diode-bridge rectifier are used to feed the inverter. The inverter feeds one...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

Abstract. Climate change impact assessment related to floods, infrastructure networks, and water resource management applications requires realistic simulations of high-resolution gridded precipitation series under a future climate. This paper proposes produce such by combining weather generator for daily precipitation, trained on historical observation-based data product, with coarser-scale cl...

Renewable energy sources face volumetric risk in their revenue streams, any electricity sale structure, due to changeability associated with weather conditions. Weather/power derivatives are often employed hedge against such financial risks. This letter proposes that a binary prediction market, if is adequately liquid, has the potential resemble function of improve profile renewable sources. Th...

Current research aims to identify the finest phase change material container construction and tries close design gap for optimum photovoltaic panel thermal management. The is used as heat sink of source thermoelectric generator. latent maximizes power generation from results show that efficiency was enhanced by 3% steady ten hours. electrical output 25% under different weather conditions. hybri...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...
