The dynamics of inertial particles in Rayleigh-Benard convection, where both particles and fluid exhibit thermal expansion, is studied using direct numerical simulations (DNS). We consider the effect of particles with a thermal expansion coefficient larger than that of the fluid, causing particles to become lighter than the fluid near the hot bottom plate and heavier than the fluid near the cold top plate. Because of the opposite directions of the net Archimedes' force on particles and fluid…

Self-sustained biphasic catalytic particle turbulence
It is found that the heat transfer enhancement is dominated by the kinematics of the active elements and their induced-agitation, which opens the door towards the establishment of tunable, ultra-high efficiency heat transfer/mixing systems.


Effects of particle settling on Rayleigh-Bénard convection.
A rather unexpected result is an unusual kind of reverse one-way coupling, in the sense that the fluid is found to be strongly influenced by the particles, while the particles themselves appear to be little affected by the fluid, despite the relative smallness of the Stokes numbers.
Effect of particle injection on heat transfer in rotating Rayleigh-Bénard convection
The present study attempts to change the regime transitions and heat transfer properties in rotating Rayleigh-Benard convection by injecting 100 µm diameter particles in the flow. The particles start

Large-eddy simulation of particle-laden turbulent flow with heat transfer
Abstract The influence of solid particles on the heat transfer rate of a non-isothermal turbulent channel flow is studied using large-eddy simulation. An Eulerian–Lagrangian approach is adopted, and
Dispersion and temperature statistics of inertial particles in isotropic turbulence
The dispersion and temperature distribution of inertial particles are important in many turbulent, multiphase flow problems. In order to understand these better, direct numerical simulations (DNSs)
Numerical experiments on strongly turbulent thermal convection in a slender cylindrical cell
