    • LEONTIDIS, Vlasios; CUVIER, Christophe; CAIGNAERT, Guy; DUPONT, Patrick; ROUSSETTE, Olivier; FAMMERY, Simon; NIVET, P.; DAZIN, Antoine (IOP Publishing, 2018)
      An ultrasonic flowmeter was developed for further applications in cryogenic conditions and for measuring flow rate fluctuations in the range of 0 to 70 Hz. The prototype was installed in a flow test rig, and was validated ...
    • JIANG, Qifeng; HENG, Yaguang; LIU, Xiaobing; ZHANG, Weibin; BOIS, Gérard; SI, Qiaorui (MDPI AG, 2019)
      Most of the pumps working under two phase flows conditions are used in petroleum industry applications, like electrical submersible pumps (ESP) for hydrocarbon fluids, in chemistry, nuclear industries and in agriculture ...
    • SI, Qiaorui; CUI, Qianglei; ZHANG, Keyu; YUAN, Jianping; BOIS, Gérard (EDP Sciences, 2018)
      In order to study the flow characteristics of centrifugal pumps when transporting the gas-liquid mixture, water and air were chosen as the working medium. Both numerical simulation and experimental tests were conducted on ...
    • ZHANG, Jian; TOUNZI, Abdelmounaim; DELARUE, Phillipe; PIRIOU, Francis; LEONTIDIS, Vlasios; DAZIN, Antoine; CAIGNAERT, Guy; LIBAUX, Antoine (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Permanent-magnet vernier machines are becoming more and more attractive due to their high torque density and low-speed operating capabilities. This paper investigates the effects of the magnet thickness, magnet pole arc ...
    • ZHANG, Xinlei; GOMEZ, Thomas; COUTIER-DELGOSHA, Olivier (Taylor & Francis, 2019)
      This paper investigates the applicability of a hybrid data assimilation approach, namely ensemble-based variational method (EnVar), to optimise Reynolds Averaged Navier-Stokes (RANS) simulations in convergent-divergent ...
    • LONG, Kunpeng; DULAR, Matevž; COUTIER-DELGOSHA, Olivier (ASME Press, 2018)
      This paper is focused on the dynamics of cloud cavitation at Sub-millimeter scales, between 0.1 and 10 mm. A simple flow configuration consisting in a small diameter jet impacting a wall at 90° and then flowing radially ...
    • ADAMA MAIGA, Mahamadou; COUTIER-DELGOSHA, Olivier; BUISINE, Daniel (AIP Publishing, 2018)
      In this paper, a new model based on bubble-bubble interactions is proposed for cavitation. Unlike the well-known existing models (Rayleigh-Plesset, Gilmore), which are derived from the local balance equations in the vicinity ...
