    A finite-volume based conservative level-set method is presented to numerically solve the non-Newtonian multiphase flow problems. One set of governing equations is written for the whole domain, and different phases are ...
  • Numerical study of droplet deformation in shear flow using a conservative level-set method

    This paper is concerned with a numerical study on the behavior of a single Newtonian droplet suspended in another Newtonian fluid, all subjected to a simple shear flow. Conservative finite-volume approximation on a collocated ...

    The computation of multiphase flows presents a subtle energetic equilibrium between potential (i.e., surface) and kinetic energies. The use of traditional interface-capturing schemes provides no control over such a dynamic ...
  • A level-set model for mass transfer in bubbly flows 

    Balcázar Arciniega, Néstor; Antepara Zambrano, Óscar; Rigola Serrano, Joaquim; Oliva Llena, Asensio (2019-08-01)
    Article
    Restricted access - publisher's policy
    A level-set model is presented for simulating mass transfer or heat transfer in two-phase flows. The Navier-Stokes equations and mass transfer (or heat transfer) equation are discretized using a finite volume method on a ...
  • Experimental investigation of inlet distortion effect on performance of a micro gas turbine 

    Naseri, Alireza; Sammak, Shervin; Boroomand, Masoud; Alihosseini, Alireza; Tousi, Abolghasem M. (2018-09-01)
    Article
    Open Access
    An experimental study has been carried out to determine how inlet total-pressure distortion affects the performance of a micro gas turbine. An inlet simulator is designed and developed to produce and measure distortion ...
