A reduced model for droplet dynamics with interfacial viscosity
Fabio Guglietta, Diego Taglienti, Mauro Sbragaglia
We propose an extension of the phenomenological Maffettone-Minale (MM) model (P.L. Maffettone and M. Minale, J. Non-Newton. Fluid Mech. 78, 227-241 (1998)) to describe the time-dep…

Deformation of ellipsoidal droplets in homogeneous and isotropic turbulence
Fabio Guglietta, Diego Taglienti, Mauro Sbragaglia
We study the statistics of deformation of neutrally buoyant droplets in homogeneous isotropic turbulence (HIT), wherein the characteristic droplet size is smaller than the char…

Droplet dynamics in homogeneous isotropic turbulence with the immersed boundary-lattice Boltzmann method
Diego Taglienti, Fabio Guglietta, Mauro Sbragaglia
We develop a numerical method for simulating the dynamics of a droplet immersed in a generic time-dependent velocity gradient field. This approach is grounded on the hybrid couplin…
