This paper presents a study of the upwelling of tropical cyclones Iván (2004) and Gustav (2008), both associated with coastal flooding in the area. The Delft3D-FLOW model was applied in order to determine its influence on the total sea surges that occurred. Graphs of sea elevation due to upwelling were obtained at La Coloma, Playa Bailen, Cabo de San Antonio, Playa Bibijagua and Carapachibey. In the absence of measured data, it was validated by comparing the results with previous studies and modeling in another area, with the presence of sea level measurement stations, but applying the same methodology. Finally, it was concluded that the application of the model under the methodology used correctly described the phenomenon. [ABSTRACT FROM AUTHOR]

The simulation of a phenomenon in a free circulation regime requires study and practice time. In the present work, recommendations are provided for the creation of models in the ANSYS Fluent software in a fast and precise way, from the evaluation of different configurations, taking as a work to model the single-cycle labyrinth weirs. The objective is to facilitate the habitual use in personal computers of this tool for its application in engineering projects. [ABSTRACT FROM AUTHOR]

In Cuba, due to the need to measure the flows that circulate through small and large diameter conductors and given the momentary impossibility of acquiring high-tech solutions in international markets, these solutions have begun to be implemented as a provisional alternative variant to carry out these measurements. This paper is a summary of the main aspects that must be kept in mind when undertaking the design and construction of a proportional flowmeter, emphasizing the potentialities and weaknesses of each of the solutions that can be implemented for such purposes.
