Scaling in large Prandtl number turbulent thermal convection
Scaling Prandtl number thermal convection
2011/7/5
We study the scaling properties of heat transfer Nu in turbulent thermal convection at large
Prandtl number Pr using a quasi-linear theory. We show that two regimes arise, depending on the
Reynolds ...
Prandtl number effects in MRT Lattice Boltzmann models for shocked and unshocked compressible fluids
lattice Boltzmann method compressible flows multiple-relaxation-time Prandtl number shock wave reaction
2011/7/7
For compressible fluids under shock wave reaction, we have proposed two Multiple-Relaxation-Time (MRT) Lattice Boltzmann (LB) models [F. Chen, et al, EPL \textbf{90} (2010) 54003; Phys. Lett. A \text...
Logarithmic Bounds for Infinite Prandtl Number Rotating Convection
Logarithmic Bounds Infinite Prandtl Number Rotating Convection
2014/4/4
Convection refers to uid motion that is induced by buoyancy. In ther-mal convection buoyancy is due to temperature di erences and one of the interesting questions is how much of the total heat transfe...

On upper bounds infinite Prandtl number convection without rotation
2014/4/4
Bounds for the bulk heat transport in Rayleigh-Benard convection for an in nite Prandtl number uid are derived from the primitive equations. The enhancement of heat transport beyond the minimal conduc...
