    • A Kalman Filter for Nonlinear Attitude Estimation Using Time Variable Matrices and Quaternions 

      Deibe Díaz, Álvaro; Antón Nacimiento, José Augusto; Cardenal, Jesús; López Peña, Fernando (MDPI, 2020)
      [Abstract] The nonlinear problem of sensing the attitude of a solid body is solved by a novel implementation of the Kalman Filter. This implementation combines the use of quaternions to represent attitudes, time-varying ...

    • A time-varying Kalman filter for low-acceleration attitude estimation 

      Deibe Díaz, Álvaro; Antón Nacimiento, José Augusto; Cardenal, Jesús; López Peña, Fernando (Elsevier, 2023-03-15)
      [Abstract]: This work shows an attitude estimator (AE) based on a time-varying Kalman filter (TVKF) and adapted to those cases where a low-acceleration assumption can be applied. This filter is an extended version of a ...

    • 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 ...

    • 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 ...

    • Mecánica de fluidos 

      López Peña, Fernando (Universidade da Coruña, Servizo de Publicacións, 2004)
      [Resumen] En este libro de texto se desarrollan los contenidos del currículo correspondiente a un primer curso de mecánica de fluidos en carreras de ingeniería mecánica, naval o similares.

    • Setting up a mixed reality simulator for using teams of autonomous uavs in air pollution monitoring 

      López Peña, Fernando; Caamaño, Pilar; Varela, Gervasio; Orjales, Félix; Deibe Díaz, Álvaro (WIT Press, 2016-08-31)
      [Abstract]: A framework based on a mixed reality simulator for coordinating teams of autonomous Unmanned Aerial Vehicles (UAVs) is been developed. This framework would serve as a tool to facilitate crossing the reality gap ...
