          Abstract

          Se presenta el estudio de algunos aspectos de la física térmica necesarios para el desarrollo de cocinas solares de pequeñas dimensiones, mediante el desarrollo de un modelo térmico semi-empirico computacional. Los parámetros libres del modelo se ajustan con datos obtenidos de un diseño experimental, que consiste en calentamiento de un fluido, exponiendo las cocinas a la radiación que produce un arreglo de lámparas incandescentes para simular la radiación solar. El modelo permite estimar algunos parámetros que sirven para comparar el funcionamiento de cocinas solares, desde el punto de vista térmico, con parámetros establecidos en protocolos estándares de prueba a nivel internacional, como por ejemplo: la potencia de cocción estandarizada y el rendimiento térmico. Utilizando el modelo no se requiere de la medición directa de radiación solar incidente y tampoco depender de las condiciones meteorológicas como días nublados o con mucho viento.

          Paper presents of some aspects of thermal physics necessary for the development of small-scale solar cookers by developing a computational semi-empirical thermal model. The free parameters of the models are adjusted with data obtained from an experimental design, which consists of heating a fluid, exposing the cooker to radiation that produces an array of incandescent lamps to simulate solar radiation. The model is useful it allows for estimate some parameters used to compare the performance of solar cookers, from the thermal point of view, with parameters established testing protocols, standards internationally, such as: standardized cooking power and thermal efficiency. Using the model does not require the direct measurement of incident solar radiation and not dependent on the weather conditions (cloudy days and wind).
