Thermal Convection for Large Prandtl Numbers [PDF]
Physical Review Letters, 2001 The Rayleigh-Benard theory by Grossmann and Lohse [J. Fluid Mech. 407, 27 (2000)] is extended towards very large Prandtl numbers Pr. The Nusselt number Nu is found here to be independent of Pr. However, for fixed Rayleigh numbers Ra> 10^{10} a maximum around Pr= 2 in the Nu(Pr)-dependence is predicted which is absent for lower Ra.

Hydromagnetic dynamos at the low Ekman and magnetic Prandtl numbers
Contributions to Geophysics and Geodesy, 2016 Hydromagnetic dynamos are numerically investigated at low Prandtl, Ekman and magnetic Prandtl numbers using the PARODY dynamo code. In all the investigated cases, the generated magnetic fields are dominantly-dipolar.

Simulation of Induction at Low Magnetic Prandtl Number [PDF]
Physical Review Letters, 2004 We consider the induction of magnetic field in flows of electrically conducting fluid at low magnetic Prandtl number and large kinetic Reynolds number. Using the separation between the magnetic and kinetic diffusive lengthscales, we propose a new numerical approach.
