Free-convection layers at large prandtl number
Zeitschrift für angewandte Mathematik und Physik ZAMP, 1971The 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.

Anomalous convection at low Prandtl number
Communications in Applied Numerical Methods, 1989AbstractThe 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 ...

Prandtl-number dependence of turbulent flame propagation
Physical Review E, 2001Inertial-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 ...

Coherent Structures and the Turbulent Prandtl Number
1989It is experimentally well established that heat spreads faster than momentum in free shear flows |1|. Thus, in the core of a jet, the turbulent Prandtl number Prt is about 0.7. Some measurements suggest that this break-down of the Reynolds analogy (which assumes Prt = 1) may be explained by the role of large-scale structures in the turbulent transport.
