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 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.
