Prototype for flow visualization with application in urban environments exposed to pollutants

This investigation presents qualitative information related to pollution in the environment in urban areas at scale, for this a prototype called convergent nozzle is designed, built and characterized in which the flow visualization technique with solids is implemented. The characterization of the te...

The characterization of the test area is carried out experimentally (using Prandtl tube) and numerically (using the commercial software Solidworks®); There is turbulent flow with recirculation at the entrance to the test area (the average speed is 4.18m/s and turbulence is 7%). With this visualization technique, the turbulent flow of different materials will be analyzed, simulating the behavior of pollutants that circulate through a prototype of a scale urban environment. Of the different materials tested, it was found that sodium bicarbonate presents the best characteristics to show the behavior of the flow around the model, clearly showing the formation of niches that simulate the accumulation of contaminants or the appearance of heat islands. Esta investigación presenta información cualitativa relacionada con la contaminación en el medio ambiente en zonas urbanas a escala, para esto se diseña, construye y caracteriza un prototipo denominado tobera convergente en el cual se implementa la técnica de visualización de flujo con sólidos. La caracterización de la zona de pruebas se realiza experimental (utilizando tubo de Prandtl) y numéricamente (utilizando el software comercial Solidworks®); se tiene flujo turbulento con recirculación en la entrada de la zona de pruebas (la velocidad promedio es de 4.18m/s y turbulencia del 7%). Con esta técnica de visualización se analizará el flujo turbulento de diferentes materiales simulando el comportamiento de contaminantes que circulan a través de un prototipo de medio urbano a escala. De los diferentes materiales probados se encontró que el bicarbonato de sodio presenta las mejores características para mostrar el comportamiento del flujo alrededor del modelo, mostrando claramente la formación de nichos que simulan el acumulamiento de contaminantes o la aparición de islas de calor.
