Regimes of heat transfer in particle suspensions
Ali Yousefi, Mehdi Niazi Ardekani, Francesco Picano +1
We present results of interface-resolved simulations of heat transfer in suspensions of finite-size neutrally-buoyant spherical particles for solid volume fractions up to 35% and b…
The effect of elastic walls on suspension flow
Marco Edoardo Rosti, Mehdi Niazi Ardekani, Luca Brandt
We study suspensions of rigid particles in a plane Couette flow with deformable elastic walls. We find that, in the limit of vanishing inertia, the elastic walls induce shear thinn…
Turbulent channel flow of finite-size spherical particles with viscous hyper-elastic walls
M. N. Ardekani, M. E. Rosti, L. Brandt
We study single-phase and particulate turbulent channel flows, bounded by two incompressible hyper-elastic walls. Different wall elasticities are considered with and without a 10%…
Turbulent duct flow with polymers
Armin Shahmardi, Sagar Zade, Mehdi N. Ardekani +4
We have performed direct numerical simulation of the turbulent flow of a polymer solution in a square duct, with the FENE-P model used to simulate the presence of polymers. First,…
Turbulence modulation in channel flow of finite-size spheroidal particles
M. Niazi Ardekani, L. Brandt
We study the effect of particle shape on the turbulence in suspensions of spheroidal particles at volume fraction and show how the near-wall particle dynamics deeply chan…
Computational modeling of multiphase viscoelastic and elastoviscoplastic flows
Daulet Izbassarov, Marco E. Rosti, M. Niazi Ardekani +4
In this paper, a three-dimensional numerical solver is developed for suspensions of rigid and soft particles and droplets in viscoelastic and elastoviscoplastic (EVP) fluids. The p…
