Magnetic fields generated by hydromagnetic dynamos at the low Prandtl number in dependence on the Ekman and magnetic Prandtl numbers

Physics of the Earth and Planetary Interiors, 2013
Abstract This article investigates the dependence of hydromagnetic dynamos on the magnetic Prandtl number at low Prandtl number. In all the investigated cases, the generated magnetic fields are dipolar and neither transition to hemispherical dynamos nor weaker magnetic fields (which are less dipole dominated) were observed, although the inertia ...

Prandtl number and thermoacoustic refrigerators

The 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.

On the Influence of the Molecular Prandtl Number on the Turbulent Prandtl Number

1979
Much more work has been done on the problem of turbulent transfer of momentum in a shear flow than on the problem of turbulent heat transfer. One of the reasons is obviously the fact, that from an experimental point of view informations about velocity-velocity correlations are easier to obtain compared with temperature-velocity correlations.

Zero-Prandtl-number convection

Journal 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.

The turbulent Prandtl number in the near-wall region for low-Prandtl-number gas mixtures

International Journal of Heat and Mass Transfer, 1996
Results of experiments for binary gas mixtures, with molecular Prandtl numbers in the range 0.18–0.7 in flow in a smooth circular tube with constant transport properties were employed to examine models hypothesized for the distribution of the turbulent Prandtl number, Prt,{{y+, Pr, Re}}.

Prandtl number for liquids

Journal of Engineering Physics, 1975
It is established on the basis of experimental data for water and toluene that: 1) the Prandtl number can be expressed in a form analogous to an equation of state; 2) there are linear relations between the Prandtl number and the transport properties.
