WebWe consider the dynamics of a vertically stratified, horizontally forced Kolmogorov flow. Motivated by astrophysical systems where the Prandtl number is often asymptotically small, our focus is the little-studied limit of high Reynolds number but low Péclet number (which is defined to be the product of the Reynolds number and the Prandtl number).

In continuum mechanics, the Péclet number (Pe, after Jean Claude Eugène Péclet) is a class of dimensionless numbers relevant in the study of transport phenomena in a continuum. It is defined to be the ratio of the rate of advection of a physical quantity by the flow to the rate of diffusion of the same quantity driven by an appropriate gradient. In the context of species or mass transfer, the Péclet number is the product of the Reynolds number and the Schmidt number (Re × Sc). In the co… WebIn the context of the transport of heat, the Peclet number is equivalent to the product of the Reynolds number and the Prandtl number. In the context of species or mass dispersion, the Peclet number is the product of the Reynolds number and the Schmidt number. For diffusion of heat (thermal diffusion), the Péclet number is defined as:
WebThe Péclet number is simply defined as the product of the Reynolds number, which describes the flow regime, and the Prandtl number, which describes the relationship … WebPeclet number (PeL) is the product of Reynolds and the Prandtl number.

WebNov 28, 2007 · Low Peclet number. For Peclet numbers smaller than 1, the diffusional motion of the solutes is fast compared to the radial velocity of the receding droplet surface. In the absence of other driving forces, the solutes remain fairly evenly distributed in the droplet during the evaporation. The surface enrichment is small. WebPeclet number is defined to be the ratio of mass transfer occurring by advection to the mass transfer occurring by diffusion. For heat transfer, Peclet number is product of Re and Pr. …
