Prandtl Number in Classical Hard-Sphere and One-Component Plasma Fluids [PDF]

open access: yesMolecules, 2021
The Prandtl number is evaluated for the three-dimensional hard-sphere and one-component plasma fluids, from the dilute weakly coupled regime up to a dense strongly coupled regime near the fluid-solid phase transition.

Prandtl number and thermoacoustic refrigerators

open access: yesThe Journal of the Acoustical Society of America, 2002
From kinetic gas theory, it is known that the Prandtl number for hard-sphere monatomic gases is 2/3. Lower values can be realized using gas mixtures of heavy and light monatomic gases. Prandtl numbers varying between 0.2 and 0.67 are obtained by using gas mixtures of helium–argon, helium–krypton, and helium–xenon.

Zero-Prandtl-number convection

open access: yesJournal of Fluid Mechanics, 1992
The zero-Prandtl-number limit of the Oberbeck—Boussinesq equations is compared to small-Prandtl-number Rayleigh—Bénard convection through numerical simulations. Both no-slip and free-slip boundary conditions, imposed at the top and bottom of a small-aspect-ratio, horizontally periodic box are considered.

Prandtl Number of Toroidal Plasmas [PDF]

open access: yesPrandtl Number of Toroidal Plasmas
Theory of the L-mode confinement in toroidal plasmas is developed. The Prandtl number , the ratio between the ion viscosity and the thermal conductivity is obtained for the anomalous transport process which is caused by the self-sustained turbulence in ...

Prandtl number effects in convective turbulence

open access: yesJournal of Fluid Mechanics, 1999
The effect of Prandtl number on the dynamics of a convective turbulent flow is studied by numerical experiments. In particular, three series of experiments have been performed; in two of them the Rayleigh number spanned about two decades while the Prandtl number was set equal to 0.022 (mercury) and 0.7 (air).

Proposal of a turbulent Prandtl number model for Reynolds-averaged Navier–Stokes approach on the modeling of turbulent heat transfer of low-Prandtl number liquid metal

open access: yesFrontiers in Energy Research, 2022
Because of their high molecular heat conductivity, low-Prandtl number liquid metal is a promising candidate coolant for various designs of advanced nuclear systems such as liquid metal–cooled fast reactors and accelerator-driven sub-critical system (ADS).
