    • Analysis of fluid hammer occurrence with phase change and column separation due to fast valve opening by means of flow visualization 

      Lema, Marcos; López Peña, Fernando; Buchlin, Jean-Marie; Rambaud, Patrick; Steelant, Johan (Elsevier, 2016-07-07)
      [Abstrac]: This paper presents an experimental investigation on the fluid hammer phenomenon generated when filling a pipe line under vacuum conditions with a closed end. This physical configuration, although it can be found ...

    • Damping of three-dimensional waves on coating films dragged by moving substrates 

      Barreiro-Villaverde, David; Gosset, Anne; Lema, Marcos; Méndez, Miguel Alfonso (American Institute of Physics, 2023-07-12)
      [Abstract]: Paints and coatings often feature interfacial defects due to disturbances during the deposition process which, if they persist until solidification, worsens the product quality. In this article, we investigate ...

    • Fluid hammer with gas desorption in a liquid- lling tube: experiments with three di erences liquids 

      Lema, Marcos; López Peña, Fernando; Rambaud, Patrick; Buchlin, Jean-Marie; Steelant, Johan (Springer, 2015-09-11)
      [Abstract]: The opening of a fast valve followed by a fluid line with a closed end generates a fluid hammer that may involve several multiphase phenomena. This is the case of the propulsion systems in satellites during the ...

    • Influence of Gas Desorption in a Safety Relief Valve Undergoing Cavitation 

      Lema, Marcos; Gosset, Anne; López Peña, Fernando (Korean Society for Fluid Machinery (KSFM), Chinese Society of Engineering Thermophysics (CSET), Turbomachinery Society of Japan (TSJ), IAHR Section on Hydraulic Machinery and Systems (IAHR), 2019-12-27)
      [Abstract]: In this study, the characterization of the flow through a safety relief valve (SRV) is performed in presence of cavitation and gas desorption. For this purpose, a transparent safety relief valve model is used ...

    • Liquid column separation due to fluid hammer occurrence in propellant lines 

      Lema, Marcos; Gosset, Anne; López Peña, Fernando; Steelant, Johan (American Institute of Aeronautics and Astronautics, 2022-10-07)
      [Abstract]: When a pressurized liquid enters a pipeline with a closed-end and under vacuum conditions, the resulting liquid front suddenly is brought to rest at the end of the pipe. This type of flow configuration is found ...
