Estudio teórico-experimental de la transferencia de calor en el tubo receptor de un colector solar de canal parabólico

Revista del Diseño Innovativo (2019)

Gustavo Valencia-Vega Moisés Montiel-González R.J. Romero Roberto Alvarado-Juárez

The capture of solar energy through parabolic trough collectors is a technological application for the use of clean energy, this allows reducing the use of fossil fuels and reducing the generation of greenhouse gases (GHG). Therefore, this article presents a theoretical-experimental study of the heat transfer in the receiver tube of a parabolic channel collector through which the working fluid flows.The receiver tube is made of copper with a nominal diameter of 1 "and is covered by a borosilicate glass tube with an outer diameter of 2 1/2" x 2.5 m long, to reduce convective losses. The theoretical study is carried out in two-dimensional (2D) Cartesian coordinates and axi-symmetric boundary condition to model and simulate fluid dynamics and analyze the behavior of convective heat transfer between the air of the annular space and the working fluid. The simulated fluid temperatures were from 80 to 180 ° C, this range includes various industrial applications where process heat is required. The simulated direct radiation values were from 600 to 1100 W / m2. The difference between the theoretical and experimental results was less than 8%.

Estudio de prefactibilidad técnica para la implementación de eco tecnologías en un establecimiento comercial del sur de Morelos

Tendencias en energías renovables y sustentabilidad . (2022)

Jesús Martínez-Domínguez Moisés Montiel-González Mariana Romero Aguilar Esteban Montiel Palacios Roberto Alvarado-Juárez

El sector residencial y no residencial ocupan la tercera posición a nivel mundial como mayores consumidores de energía eléctrica. En México, el sector no residencial consume el 17.6 % de la energía total del país, por lo que tienen una gran huella de carbono debido a la producción de la energía eléctrica derivada de la quema de combustibles fósiles. Dentro de los edificios que componen a este sector se encuentran los establecimientos comerciales, los cuales, en su mayoría tienen muy alta demanda de energía, ya que, deben ser competitivos a nivel comercial y brindar confort térmico a los ocupantes del edificio, por lo que, sistemas de aire acondicionado o calefacción, la iluminación, además de la refrigeración de productos, son áreas de prioridad para los establecimientos comerciales, dicho esto, es necesario proponer alternativas para reducir su consumo energético sin comprometer sus actividades sustanciales. En este trabajo se realiza un estudio de prefactibilidad técnica en un establecimiento comercial ubicado en Jojutla, Morelos, con el objetivo principal de generar una propuesta para la posible implementación de eco tecnologías como pozos canadienses o provenzales y así proporcionar confort térmico al interior del edificio, así como un sistema solar fotovoltaico para el suministro de energía eléctrica al establecimiento comercial.

Numerical study of the Boussinesq approach validity for natural convection and surface thermal radiation in an open cavity

Revista Mexicana de Física (2013)

Moisés Montiel-González Jesús Hinojosa Palafox Claudio Estrada Gasca

In this work the validity of the Boussinesq approach for the heat transfer calculations in an open cavity considering natural convection and surface thermal radiation is studied. Numerical calculations were conducted for Rayleigh number (Ra) values in the range of 10 4 -10 6 . The temperature difference between the hot wall and the bulk fluid ( ¢T) was varied between 10 and 100 K, and was represented as a dimensionless temperature difference (’). The deviations for the temperature fields and fluid flow patterns, between variable properties and Boussinesq approach are noticeable for ’=0.333. For total Nusselt numbers, the results with Boussinesq approach and variable properties, indicates deviations within 0.22 % (Ra=10 5 and ’=0.033) and 5 % (Ra=10 4 and ’=0.333).

Effective removal of fecal coliforms from river water in a rural community using low-cost CPC

Energy Sources Part A Recovery Utilization and Environmental Effects (2022)

Teresa Hernández-Ortíz Iván Salgado‐Tránsito Carlos A. Pineda‐Arellano Josefina Vergara-Sánchez Moisés Montiel-González

This paper presents the design, manufacture, characterization, and evaluation of a solar disinfection (SODIS) reactor based on compound parabolic concentrators (CPCs). Two materials were used to manufacture the reflective surface of the CPCs, high reflectivity aluminum sheet (CPCHRS) and commercial aluminum foil (CPCAF). In both configurations, the solar energy collection area, the concentration ratio, and the volume capacity were the same, 1 m2, 1-Sun and 100 L per day, respectively. CPC-type reactor was manufactured with low-cost materials affordable for the end user in rural communities. The experimental evaluation was carried out under real-life conditions using water from a river consumed by the inhabitants of a rural community in Mexico. The effectiveness of CPCs for disinfection using the SODIS process was demonstrated using a flow rate of 10 L/h. CPCHRS achieved 100% bacterial removal of fecal coliforms in 2 h of solar exposition, while CPCAF reached the same results in 4 h under similar conditions. Solar disinfection of natural freshwater sources using a CPC type reactor shows the feasibility of eliminating the main microorganisms that cause gastrointestinal diseases, thus improving the quality of life of the rural community.

MODEL FOR THE ANALYSIS OF INTRALAMINAR THERMAL STRESSES IN LAMINATED COMPOSITES MATERIALS

DYNA (2019)

Juan José Delfín Vázquez Mario Acosta Flores Eusebio Jiménez López BALDOMERO LUCERO VELAZQUEZ Moisés Montiel-González

When a structural element is manufactured with a laminated composite material (MCL) and this is subjected to temperature changes, intralaminar thermal stresses are generated. The intralaminar thermal stresses occur due to the differences among the coefficients of thermal expansion and the elastic properties of the layers that make up the MCL. It is possible that a combination of intralaminar stresses and mechanical stresses will produce faults by separation in the MCL layers (delamination). In this article we presents an analytical model with which global and intralaminar thermal stresses produced by temperature changes induced in symmetric metallic MLCs are calculated, without restrictions at the borders. The model is fed by deformation data obtained by strain gauges placed at the border of the MLC. The model can be used in the determination of intralaminar and global stresses considering restrictions or loads at the border, only if the problem is of flat stresses. The model was developed by making an analogy to the analytical model developed in [1], which consists of calculating intralaminar and global stresses that are generated by the difference between the elastic constants of the materials that make up an MCL subjected to simple tension. The proposed model is based on the theory of linear elasticity, the classical theory of plates and the principle of superposition. With the model and through an array of experimental tests, the coefficients of thermal expansion (CET) of each of the layers can be calculated. Finally, experimental validation tests were carried out which showed that the proposed model is reliable and consistent.
