In the present paper, a quantitative and qualitative evaluation of the wind resource was carried out in order to characterize the exploitable potential of the wind resource in the area around the city of Juliaca in the Puno region. The data provided for the years 2013-2014 by the National Service of Meteorology and Hydrology of Peru - SENAMHI, of the station located in this city, were analyzed to compare with the database of NASA (Surface Meteorology and Solar Energy. SSE, 2012). The quantitative analysis consisting of the characterization of the average hourly and monthly wind speed for a height of 25 m above the ground, comparing the average monthly speeds of NASA and SENAMHI, shows an average difference of 8.93% during the months of spring and summer, where the wind also exceeds 3 m/s, and the predominant directions of the wind is the west and the east. The qualitative analysis corres...

The design, construction and evaluation of a parallel dual-flow air heater solar collector that has the V-shaped corrugated absorbent plate and that works by natural convection is presented. The collector has been evaluated for clear sky when installed on a vertical wall in the city of Puno, oriented towards the geographical north in the autumn season. The performance parameters allowed to obtain high efficiency and the construction is low cost. The maximum outlet air temperature of the collector reached 95,7 ºC for a solar intensity of 758 W/m2, and the average mass flow for sunny days was 0,0094 kg/s, in addition it was found that the mass flow is very sensitive to air velocity and density. The average efficiency of the collector is 51,1% which represents a good performance since it extracts a large amount of completely passive thermal energy without requiring additional external ener...

The effect of the porous bed in a solar air heater with a V-corrugated absorbent plate and a design that facilitates free convection is analyzed, in terms of performance parameters and thermal efficiency. The collector was evaluated, with and without porous bed, under similar climatic conditions when mounted on a vertical wall. The results revealed that the mass flow is directly affected by the ambient temperature. It was observed that the porous bed affects the laminar sublayer of the absorbent plate generating greater turbulence that improves the rate of heat transfer, therefore, the collector with a porous bed presents a higher temperature inside and slightly decreases its efficiency. In addition, the porous bed works as a heat store that reduces instabilities which allows a uniform outlet temperature and allows to increase the operating time. The collector is inexpensive, respectful ...

El objetivo del presente trabajo es diseñar, construir y evaluar teórica y experimentalmente el rendimiento termo-energético de un colector solar calentador de aire (CSCA) de doble flujo en paralelo que opera por convección natural, que tiene una placa absorbente corrugada en forma de V que fue evaluado al instalar sobre una pared vertical en la ciudad de Puno. Para evaluar sus parámetros de operación y las eficiencias, se estudiaron dos configuraciones del colector, la primera (tipo I) es el colector diseñado sin la malla porosa, y la segunda (tipo II) es el colector con una malla porosa de virutilla de hierro en el canal entre la placa absorbente y la parte posterior del colector. La temperatura máxima de salida del aire del colector de tipo I y II alcanzaron en promedio 94,6 ºC y 95,4 ºC respectivamente, y el flujo másico promedio para días soleados fue de 0,0094 kg/s y 0,...

Los programas de reforma liberal en los países en desarrollo no fueron diseñados con la necesidad de ampliar el suministro de electricidad a las zonas rurales. Esta investigación se centra en la experiencia peruana, que examina el impacto de las políticas de reforma de la electricidad de las características de la electrificación rural. En las zonas rurales áreas, niveles de electrificación han sido tradicionalmente los más bajos del país haciendo que sea menos o no rentable para las empresas privadas. Solo en 2002, El gobierno introduce una ley específica de electrificación rural, que tenía por objeto promover la electrificación en el contexto de un mercado liberalizado. Este documento se basa en un análisis tanto esta pieza de legislación y entrevistas de las partes interesadas, lo que indica que existe una necesidad de mirar más allá en la evolución de las relaciones...

La calidad del agua se clasifica en diferentes categorías en función a la presencia de fuentes contaminantes, en el 2018 el Perú adoptó el modelo canadiense “ICA-PE” instrumento con el que se puede evaluar la variación de la calidad de las aguas superficiales. En el presente estudio se evaluó la variación de la calidad del agua del río Coata en el tramo puente Maravillas –  Puente  Coata  debido  a  la  existencia  de  fuentes  contaminantes.  Para  establecer la variación de la calidad del agua se identificaron los puntos de muestreo: ACFC-01, DCFC-03 y DCFC-05 y las fuentes de contaminación: FC-02, y FC-04, a partir de los cuales se analizaron 18 parámetros requeridos para el cálculo del ICA-PE, los parámetros se analizaron de acuerdo a los métodos normalizados para el análisis de agua potable y residual (AWWA-APHA-2001). Las aguas del río Coata en el t...
