Free-convection layers at large prandtl number

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1971
The behavior of laminar free-convection boundary layers at large Prandtl number is considered. Plane and axisymmetric flows are treated simultaneously in terms of a unified formulation. Flow and heat-transfer quantities are expressed in terms of expansions within an inner and an outer layer, both of which lie inside the Prandtl's viscous layer.

Turbulente Prandtl-Zahl Prt (turbulent Prandtl number Prt)

2000
Es handelt sich urn eine Stromungsgrose (keine Stoffgrose), die in Analogie zur molekularen Prandtl-Zahl (einer Stoffgrose) eingefuhrt worden ist. Sie ist keine dimensionslose Kennzahl im Sinne der Dimensionsanalysis.

Anomalous convection at low Prandtl number

Communications in Applied Numerical Methods, 1989
AbstractThe steady‐state natural convection of a fluid of low Prandtl number contained within a two‐dimensional rectangular box is simulated for conditions of an imposed horizontal temperature gradient and conducting horizontal surfaces. By the application of numerical bifurcation and continuation techniques combined with the finite‐element method the ...

Rotating convection at moderate Prandtl number

Physica A: Statistical Mechanics and its Applications, 1998
Abstract A small rotation is shown to inhibit the spiral chaos which develops in Rayleigh–Benard convection at moderate Prandtl number. Near the critical rotation for the onset of the Kuppers–Lortz instability, large coherent targets embedded in a turbulence background are formed in the case of free-slip top and bottom boundary conditions, while in ...

Turbulent Thermal Convection at Arbitrary Prandtl Number

The Physics of Fluids, 1962
The mixing-length theory of turbulent thermal convection in a gravitationally unstable fluid is extended to yield the dependence of Nusselt number H/H0 on both Prandtl number σ and Rayleigh number Ra. The analysis assumes a layer of Boussinesq fluid contained between infinite, horizontal, perfectly conducting, rigid plates.

Prandtl-number dependence of turbulent flame propagation

Physical Review E, 2001
Inertial-range cascade phenomenology is used to predict Prandtl-number (Pr) dependencies of turbulent flame properties. A unified picture of turbulent flame structure and burning velocity is developed that encompasses all Pr regimes. Implications of the analysis for gaseous flames (Pr near unity), autocatalytic fronts in liquids (high Pr), and ...
