Published: August 2023

Vertical Axis Wind Turbine (VAWT) is relatively simple to implement in urban areas on ground or/and building-roofs, the development of appropriate design of VAWT will open new opportunities for the large-scale acceptance of these machines. The primary objective of this research was to design and modeling of a small-scale VAWT, which can be used to meet the power for low demand applications. Two new shapes of Savonius rotor blades were examined in terms of their rotational performances against the conventional straight and the curved blades. MATLAB simulation was utilized to develop a mathematical model, which comprised of wind power coefficient, tip speed ratio, mechanical and electrical subcomponents. The measured results of developed turbine were used for the validation of the model. The aims were to analyze the turbine blade shapes, develop a mathematical algorithm, and to establish the techno-economic performance of the new curved shape design. It was modeled that the proposed turbine is capable of producing an annual energy output of 7838 kWh and the annual electricity cost/saving in Ontario turned out to be $846.51 (the price of electricity was taken $0.108/kWh).

Authors: Kamel Raghad Sabah , Fung Alan
Published: August 2023

This paper is intended to develop a detailed thermal and electrical model of a transparent backing Building Integrated Photovoltaic/Thermal (TBIPV/T) collector integrated to the roof. This model was used to assess the energy performance of a typical transparent PVT air collector. The energy balance equations were derived for glazing glass, the PV cells, glass back surface of the PV module, air flowing in the duct of TBIPV/T collector and back insulation surface. The energy equations were solved using FORTRAN. A new TRNSYS type was created for the transparent backing PVT system. This type is intended to function with multi-zone building model in TRNSYS, that means thermal interaction between the PV/T collector and the building was taken into account. The effect of different PVT system parameters such as PV cell packing factor, panel cover optical properties on thermal energy production and electricity generation were examined and discussed.

Published: August 2023

The purpose of the research is to determine the traction resistance when the bucket is operating on the rigid guides of the RR-303 channel cleaner, depending on the change in the main factors. The RR-303 channel repairer diﬀers from many currently used designs of canal cleaning machines by the movement of the cleaning bucket strictly straight along the axis of the channel on rigid guides. In addition, according to the mode of operation, the channel cleaner refers to machines of periodic action, which positionally cleans the bottom of the channel and the slopes adjacent to the bottom. The working equipment of the channel repairer includes a twin telescopic boom, rigid guides (based on two channels) is installed as a side linkage on the DT-75 tracked tractor. There are also design projects of working equipment designed for installation on a more modern basic tractor VT-100. The main attention in the design of the working equipment of the channel cleaner was paid to the possibility of ensuring high quality cleaning work with the lowest traction resistance. The high quality of work is mainly ensured by the rectilinear movement of the bucket along the rigid guides. The value of traction resistance, as a target function or optimization parameter, is most inﬂuenced by the thickness of the soil chips, the density of the soil in terms of the diﬃculty of its development and soil moisture. The presence of these three characteristics, which can be called factors, give reason to believe that their change aﬀects the traction resistance of the bucket of the channel cleaner in the process of its operation is much greater than, for example, the cutting angle or laying slopes. Accordingly, in this study, the following three are taken as the main factors aﬀecting the target function: change in chip thickness; changes in soil density in terms of development diﬃculty; change in the value of soil moisture. Determination of traction resistances during the operation of the channel cleaner bucket model was carried out using the method of three-factor study, which allows to estimate the value of the most signiﬁcant factor aﬀecting the target function, in this case the traction resistance. Processing of the results of laboratory studies was carried out using the methods of statistical analysis and computer programs Mathcad and Excel.

El consumo de agua en grandes volúmenes debido a la alta demanda de hormigón provoca también un impacto ambiental de gran relevancia en zonas donde se extrae dicho recurso. El objetivo de esta investigación es identificar aspectos ambientales de la producción de hormigón que sean relevantes en Panamá, así como información disponible sobre estos aspectos ambientales en el país. En Panamá, a pesar de la importancia y uso del hormigón, no se cuenta con datos de consumo de agua, energía y emisiones de CO2. De ahí la importancia de realizar un levantamiento cualitativo y cuantitativo de los procesos de producción de hormigón en Panamá incluyendo aspectos ambientales. Se busca que los resultados obtenidos sirvan de base para posteriormente ejecutar las acciones necesarias a nivel de propuestas y uso de tecnologías y elaboración de políticas públicas.

Un camino a concretar los ideales de eficiencia energética es el uso de aislamientos térmicos. Cuando se selecciona un aislamiento se deben tomar en cuenta varios factores: la disponibilidad, el costo de aplicación, impacto ambiental y energético. Los aislamientos naturales juegan un papel fundamental en el futuro de las edificaciones sustentables. Cuando se habla de edificaciones sustentables se refiere a construcciones, remodelaciones y reacondicionamiento de los edificios, usando prácticas y materiales que no dañen al medio ambiente, con los cuales se obtengan beneficios como lo son: control de la temperatura, uso de materiales naturales y energía propia. Este proyecto, se realizó con el objetivo de evaluar y analizar el desempeño de la paja canalera (Saccharum spontaneum), mediante el estudio teórico, el diseño y fabricación de placas rígidas que contribuyan al mejoramiento de las condiciones térmicas en los espacios interiores, utilizando un prototipo de caja caliente basada en la norma ASTM C177 y la ley de Fourier de transferencia de calor.Para los ensayos se fabricó una placa que contenía la mezcla de paja canalera triturada y goma blanca industrial. A fin de determinar la conductividad térmica se procedió a la aplicación de calor de forma constante, para posteriormente determinar el gradiente de temperatura. Los datos obtenidos permitieron conocer de forma relativa la conductividad térmica de la placa confeccionada.

Una inversión en rehabilitación o reconstrucción de una calle es sumamente mayor al costo del mantenimiento de los pavimentos. De acuerdo con esto, este estudio tiene como objetivo exponer el estado de las tres calles en el corregimiento de David Sur, debido a el nulo mantenimiento, mala construcción y al alto volumen de tráfico. Además, se busca promover el uso del PCI (Pavement Condition Index), ya que en nuestro país es un método poco implementado. Por estos motivos, surge la decisión de usar el método conocido como PCI, que está dentro de la norma ASTM D6433-20. Los resultados obtenidos de las tres calles evaluadas fueron condición grave (Calle M Sur), condición Pobre (Calle Z Sur) y condición pobre (Calle 1ra), resaltando lo mencionado anteriormente que la gran mayoría de las calles se encuentran en mal estado con una calidad de viaje mala o pésima. Cabe resaltar que el método al existir fallas que se deben categorizar según el aspecto visual o la calidad de viaje depende en gran medida de la consideración del propio inspector o persona que evalúa la calle. También existen otros métodos conocidos para evaluar pavimentos; sin embargo, resaltamos el uso del método PCI ya que globaliza múltiples fallas causadas por distintos factores con un gran acierto a la condición real de pavimento y la comparación de estas clasificaciones con otros métodos como por ejemplo el IRI (International Roughness Index) que incluso existe una posible correlación entre los dos métodos de evaluación que también se presentará en el artículo.

El agua potable es un recurso indispensable que el Estado debe proveer. Sin embargo, las cuencas hidrográficas se ven cada vez más afectadas y la demanda del agua va en aumento. Esto se traduce en la necesidad de hacer un mejor uso de los recursos disponibles y poner en práctica la investigación científica como una herramienta para la toma de decisiones, mediante metodologías innovadoras. En este sentido, este trabajo describe el procedimiento utilizado para simular, matemáticamente, el pre-floculador de la potabilizadora Jaime Díaz Quintero de La Chorrera. Esta simulación se realizó en el software OpenFoam aplicando las ecuaciones de Navier-Stock promediadas por Reynolds con el modelo turbulento de transporte de esfuerzos cortantes k-omega (SST, por sus siglas en inglés). Para esto se trabajó un modelo 3D del pre-floculador y se simplificaron sus características mediante AutoCAD y Blender. Adicionalmente, la discretización del dominio se realizó mediante el algoritmo cfMesh de OpenFoam y se utilizó el software Paraview para observar los resultados. La simulación se llevó a cabo con una computadora de 64 GB de RAM y 24 núcleos. Los resultados mostraron residuales del orden de 0.001 y se obtuvieron valores de y+ dentro del rango aceptable con un máximo de 37. En cuanto al campo de velocidad, la simulación mostró los flujos y su bifurcación debido a la presencia de los tablones con magnitudes entre 0.6 m/s cerca de la entrada y 0.2 m/s del otro lado del muro divisorio. Se obtuvo un modelo no calibrado con sentido físico.

Dentro de los materiales de construcción que poseen tendencia a mostrar alzas significativas en sus precios debido a agentes variables se encuentra el cemento, siendo este un material de construcción imprescindible en la región. Este artículo estudia la factibilidad de una propuesta de reemplazo del porcentaje de material cementante en morteros de cemento hidráulico por un elemento de menor costo e impacto ambiental, cenizas de hojas de bambú (CHB), del cual varios autores indican que poseen propiedades puzolánicas considerables. Se presenta el procedimiento completo para la obtención de este material suplementario, que va desde la recolección de las hojas de bambú, su secado, triturado e incineración para la obtención de las cenizas. El estudio pretende justificar el uso de las cenizas de hojas de bambú en morteros a través del análisis de los resultados de ensayos de resistencia a la compresión, con el fin de evaluar su resistencia. Durante este estudio se obtuvieron resultados prometedores en los ensayos de resistencia a la compresión de los morteros que incorporan CHB, tanto a edades de ensayo tempranas (24 horas, 3 días y 7 días), como a edades avanzadas de ensayo de 28 días y 56 días, en los cuales las resistencias a compresión de los morteros con CHB fueron superiores o muy similares a las resistencias de los morteros control, teniendo estos resultados implicaciones importantes en el desarrollo de nuevos materiales sostenibles con potencial futuro a implementarse en la industria del concreto.

La contaminación por el plástico en Panamá es abundante, y a pesar de que se hacen muchos proyectos para erradicarla este sigue convirtiéndose en algo inevitable por lo tanto hemos decidido hacer una investigación siguiendo patrones de investigaciones existentes para darle un uso provechoso: Unos bloques de concreto que contengan plástico PET triturado para darle un mejor uso. Los bloques prototipos fueron realizados con cemento, arena, gravilla y plástico triturado. Para la elaboración primero añadimos arena, después gravilla, luego cemento y, por último, plástico PET transparente triturado, lo mezclamos y fuimos añadiendo poco a poco agua hasta lograr una consistencia buena. Se hicieron varios prototipos hasta que saliera un bloque lo suficientemente bueno, es decir que la cantidad de material fueron variando hasta que encontráramos los porcentajes de materiales ideales para hacer que este resista y pueda ser utilizado de manera adecuada. El prototipo final utilizó 15 % de arena, 30 % de gravilla, 27 % de plástico PET triturado, 16 % de cemento estructural y 12 % de agua obteniendo una buena consistencia y denso.

Este estudio tiene como objetivo evaluar las metodologías disponibles para estimar el potencial de licuación de suelos, utilizando como caso de estudio la Ciudad de David, Provincia de Chiriquí. En primera instancia, se realizó una revisión bibliográfica de ocurrencia de sismos a nivel mundial donde se registró el fenómeno de Licuación; también se identificaron metodologías aplicables para determinar el Potencial de Licuación del suelo. Luego, se creó y analizó una base de datos de sondeos realizados en la Ciudad de David y se evaluó el Potencial de Licuación en diferentes condiciones para cada uno de estos sondeos implementando una hoja de cálculo creada con los métodos aplicables. Los resultados indicaron que, a mayor magnitud del sismo, mayor era el potencial de licuación para las condiciones evaluadas. Se espera que este estudio sirva como punto de partida para crear una metodología que permita evaluar la vulnerabilidad sísmica de tuberías de agua potable en diferentes áreas del país, como parte importante en el Proyecto IOMA 19-011 “Vulnerabilidad Sísmica de Redes de Agua Potable en Panamá”. Se recomienda analizar otros fenómenos que son consecuencias de los sismos y realizar una caracterización apropiada de las áreas que se definan para realizar los estudios, creando bases de datos que puedan ser utilizadas por diferentes investigadores que deseen cooperar con sus conocimientos y habilidades.

Indonesia Pilot Academy utilizes language as an impactful tool to affect people’s perceptions. An electronic website is becoming increasingly vital for academy and candidate cadets by employing language as information and representation. The portrayal of Indonesia Pilot Academy represents the use of linguistic representation on the website and the contribution of this to understanding the overlapping factors that reinforce academic practices within the Indonesia flight-social structure. There are unanswered questions related to the study comparing and analyzing the diverse discourses used to represent Indonesia flight academy on its website regarding social constructs (e.g., gender and race). Then, the study aims to determine website language represented as academic quality, product, and social construct. The data was taken from the website of the academy. To that end, critical discourse analysis (CDA) is utilized to describe, analyze, and interpret the textual and visual representations of the Indonesia Pilot Academy website at the local, institutional, and societal levels. What is surprising is that the academy should encourage global political involvement with promotional discourse and visual images. This finding has important implications for fostering international promotional discourse and pictures to emphasize prestige and uniqueness.
