    • Effect of a commercial air valve on the rapid filling of a single pipeline: A numerical and experimental analysis 

      Coronado Hernández, Óscar Enrique; Besharat M.; Fuertes Miquel, Vicente S.; Ramos H.M. (MDPI AG, 2019)
      The filling process in water pipelines produces pressure surges caused by the compression of air pockets. In this sense, air valves should be appropriately designed to expel sufficient air to avoid pipeline failure. Recent ...

    • Effect of deficit irrigation on yield, quality, and costs of the production of native spearmint 

      Nakawuka P.; Peters T.R.; Gallardo K.R.; Toro González, Daniel; Okwany R.O.; Walsh D.B. (American Society of Civil Engineers (ASCE), 2014)
      Water-saving strategies aimed at improving water use efficiency need to be applied in agriculture today to ensure sustainable use of scarce water resources. This article presents results of a 2-year study done at Washington ...

    • Experimental and numerical analysis of a water emptying pipeline using different air valves 

      Coronado Hernández, Óscar Enrique; Fuertes Miquel, Vicente S.; Besharat M.; Ramos, H.M. (MDPI AG, 2017)
      The emptying procedure is a common operation that engineers have to face in pipelines. This generates subatmospheric pressure caused by the expansion of air pockets, which can produce the collapse of the system depending ...

    • Transient phenomena during the emptying process of a single pipe with water–air interaction 

      Fuertes Miquel, Vicente S.; Coronado Hernández, Óscar Enrique; Iglesias-Rey P.L.; Mora-Meliá D. (Taylor and Francis Ltd., 2019)
      Emptying pipelines can be critical in many water distribution networks because subatmospheric pressure troughs could cause considerable damage to the system due to the expansion of entrapped air. Researchers have given ...

    • Vehicular road influence areas 

      Huertas M.E.; Huertas, J.I.; Valencia A. (Elsevier Ltd, 2017)
      Vehicle operation over paved and unpaved roads is an emission source that significantly contributes to air pollution. Emissions are derived from vehicle exhaust pipes and re-suspension of particulate matter generated by ...
