On the terminal velocity of sedimenting particles in a flowing fluid
Marco Martins Afonso
The influence of an underlying carrier flow on the terminal velocity of sedimenting particles is investigated both analytically and numerically. Our theoretical framework works for…
Fluid-particle separation in the Batchelor regime with telegraph model of noise
Marco Martins Afonso
We study the statistics of the relative separation between two fluid particles in a spatially smooth and temporally random flow. The Lagrangian strain is modelled by a telegraph no…
Fluid-particle separation in a random flow described by the telegraph model
Gregory Falkovich, Marco Martins Afonso
We study the statistics of the relative separation between two fluid particles in a spatially smooth and temporally random flow. The Lagrangian strain is modelled by a telegraph no…
Does multifractal theory of turbulence have logarithms in the scaling relations?
Uriel Frisch, Marco Martins Afonso, Andrea Mazzino +1
The multifractal theory of turbulence uses a saddle-point evaluation in determining the power-law behaviour of structure functions. Without suitable precautions, this could lead to…
Nonlinear elastic polymers in random flow
M. Martins Afonso, D. Vincenzi
Polymer stretching in random smooth flows is investigated within the framework of the FENE dumbbell model. The advecting flow is Gaussian and short-correlated in time. The stationa…
