Cross-flow oscillations of a circular cylinder with mechanically coupled rotation
Alessandro Nitti, Giovanni De Cillis, Marco . D. de Tullio
Flow-Induced Vibrations (FIV) of an elastically mounted circular cylinder are investigated by means of two-dimensional simulations. A mechanical coupling between cross-flow transla…
A priori tests of turbulence models for compressible flows
Sciacovelli L., Cannici A., Passiatore D. +1
A priori tests of turbulence models for the compressible Reynolds-Averaged Navier--Stokes (RANS) are performed by using Direct Numerical Simulations (DNS) data of zero-pressure-gra…
Predicting the vascular adhesion of deformable drug carriers in narrow capillaries traversed by blood cell
A. Coclite, G. Pascazio, M. D. de Tullio +1
In vascular targeted therapies, blood-borne carriers should realize sustained drug release from the luminal side towards the diseased tissue. In this context, such carriers are req…
Characterization of micro-Capsules Deformation in Branching Channels
Alessandro Coclite, Marco D. de Tullio, Giuseppe Pascazio +1
In this paper, the dynamic of inertial capsules into microfluidic bifurcations is studied. The fluid evolution is based on the solution of the BGK -- lattice Boltzmann scheme inclu…
A Lattice Boltzmann dynamic-Immersed Boundary scheme for the transport of deformable inertial capsules in low-Re flows
Alessandro Coclite, Sergio Ranaldo, Giuseppe Pascazio +1
In this work, a dynamic-Immersed--Boundary method combined with a BGK-Lattice--Boltzmann technique is developed and critically discussed. The fluid evolution is obtained on a three…
Kinematic and dynamic forcing strategies for predicting the transport of inertial capsules via a combined lattice Boltzmann-Immersed Boundary method
A. Coclite, S. Ranaldo, M. D. De Tullio +2
Modeling the transport of deformable capsules under different flow regimens is crucial in a variety of fields, including oil rheology, blood flow and the dispersion of pollutants.…
