This study aims to build a potential map for the installation of central receiver concentrated solar power plant in Chile under terms average net present cost electricity generation during its lifetime. is also called levelized electricity, which function production, capital costs, operational costs and financial parameters. The were defined as location through Chilean territory. Solar resources atmospheric conditions each site determined. A 130 MWe was modeled estimate annual production...
This paper describes the design of a prosthetic hand for wrist amputations. The mechanism considers use three actuators: one each movement little finger, annular and middle finger. second actuator controls index third thumb. prototype is considered relevant as it able to move distal phalanx in all fingers; little, annular, fingers are adapt shape object being gripped (adaptive grip). sequence movements achieved with thumb emulate opposition/reposition flexion/extension movements, commanded...
Abstract This study presents a novel algorithm to evaluate the power losses in photovoltaic (PV) modules that are exposed naturally accumulated soiling. The proposed uses red, green, and blue (RGB) images of PV captured visible spectrum measures features such as average color intensity standard deviation from every channel. These then ranked based on module performance by using statistical tools, most relevant set is selected. selected used an input, generation label train artificial neural...
The challenges encountered while concentrating solar radiation from multiple heliostats into a relatively small receiver have inspired numerous aiming methodologies to distribute such concentrated radiation. Likewise, this radiation, denominated heat flux, needs satisfy certain constraints that primarily depend on the geometry, its building materials, operating mass flow of transfer fluid, and overall conditions. A recent study has demonstrated effectiveness an strategy wherein group use...
The bit–rock interaction is a key point in the fracture process observed excavation applications, which makes its analysis relevant. As discrete element method (DEM) has been successfully applied to study rock breakage behavior, we apply it present analyze various aspects of interaction. This research focuses on numerically analyzing interaction, encompassing force penetration relationship (FPR), mechanical energy transfer rock, and efficiency process. In order perform this analysis,...
Sun-powered desalination technologies, such as humidification-dehumidification (HDH), are an attractive alternative to provide freshwater in remote high-radiation climate conditions.In this work, experimental and numerical study is presented for a solar HDH unit operating with closed air-open water configuration water-heated collectors.The model shows good agreement data both temperature distillate production.A new performance parameter, so-called distillate-to-irradiance ratio (DIR),...
One of the failures in solar receivers is usually produced by thermal stresses caused non-uniformity concentrated flux and transient behavior climate.The use liquid sodium as a heat transfer fluid allows to reach higher temperatures feed more efficient power systems, however, this produces an increase stresses, putting safety facilities at risk.The change geometry alternative improve thermo-mechanical receiver tubes.To compare hydraulic characteristics, parameters such Reynolds number,...
This paper proposes a novel method based on Monte Carlo Ray Tracing for high-precision and low time computation processing of view factors in random assemblies cylindrical packed beds. The is improved by coupling it with Kowsary’s tangent sphere under the parallel through Compute Unified Device Architecture, showing reduction computational approximately 153 times less than traditional hardware used obtaining maximum relative error 0.39% configurations evaluated literature. Furthermore,...
