1. The magnetic Prandtl number is an important property of the fluid. 2. Its counterpart the Prandtl number is employed in laminar flow calculations. 3. The ratio of the two thicknesses is governed by the Prandtl number . 4. That is, the Prandtl number is given as: 5. The Rayleigh number ( Ra ) is the product of the Grashof and Prandtl numbers . 6. If the Prandtl number is 1, the two boundary layers are the same thickness. 7. The turbulent Prandtl number has been shown to not generally equal unity ( e . g. 8. The Turbulent Prandtl number is a non-dimensional parameter required in convective turbulent heat transfer calculations. 9. In heat transfer problems, the Prandtl number controls the relative thickness of the momentum and thermal boundary layers. 10. They developed relationships between the turbulent and moleculer Prandtl number that can be employed in convective heat transfer calculations.
