La utilización de aire caliente en diversos procesos hace necesario el desarrollo de investigaciones que hagan más eficientes y económicos los métodos de producirlo, donde la primera opción por evaluar son los colectores solares. Este trabajo desarrolla una modelación de un colector solar de placa plana y lecho poroso, empleando la solución de ecuaciones analíticas en diagramas de bloques, para estructurar un software que permite simular el comportamiento del colector en estado transitorio, bajo diversos parámetros. En la aplicación se evalúa teóricamente el comportamiento del lecho poroso, la eficiencia, la caída de presión, la distribución de temperaturas y los materiales empleados para su construcción. Esto permite un análisis del comportamiento térmico, con un error promedio comparado con resultados experimentales de 6 %. El modelo se valida experimentalmente, con datos de un colector real, donde se mantiene un flujo de aire de 0,119 kg/s y se varía la radiación entre 400 y 500 W/m2; se observa la distribución de temperaturas, la eficiencia térmica y las caídas de presión. En los resultados obtenidos se alcanzan temperaturas de 360 y 375 K en el aire de salida y caídas de presión de 10,27 y 14,27 Pa, con valores de eficiencia de 36,5 y 51,7%, respectivamente, para nivel de radiación. Esto demuestra la idoneidad de este tipo de colectores como una opción para captar energía solar. 2014-04-09 2019-09-19T21:53:20Z 2019-09-19T21:53:20Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.udistrital.edu.co/index.php/visele/article/view/5509 10.14483/22484728.5509 http://hdl.handle.net/11349/21817 spa https://revistas.udistrital.edu.co/index.php/visele/article/view/5509/7039 https://revistas.udistrital.edu.co/index.php/visele/article/view/5509/7225 Derechos de autor 2013 Visión Electrónica: algo más que un estado sólido application/pdf text/html Universidad Distrital Francisco José de Caldas Visión electrónica; Vol 7 No 2 (2013); 57-66 Visión electrónica; Vol. 7 Núm. 2 (2013); 57-66 2248-4728 1909-9746
