Image and Reality: Kekule, Kopp, and the Scientific Imagination

Nineteenth-century chemists have been confronted with a selected challenge: how you can depict the atoms and molecules which are past the direct succeed in of our physically senses. In visualizing this microworld, those scientists have been the 1st to maneuver past high-level philosophical speculations in regards to the unseen. In snapshot and truth, Alan Rocke makes a speciality of the neighborhood of natural chemists in Germany to supply the foundation for a fuller knowing of the character of clinical creativity.

When the scale of the spatial averaging is much smaller than we approach the LES limit (right side) where the energy-containing turbulence is resolved. ergodicity, to ensemble averaging, and thus to time averaging in stationary conditions. That allows one to use micrometeorological observations to determine behavior in the mesoscale limit. 9) are the formal evolution equations for the deviatoric stress τij and kinetic energy E of the unresolved motions in LES, in mesoscale modeling, and for applications over the vast range of scales in between.

4 The “terra incognita” 31 As h → we approach the energy-containing range; we enter it when h becomes less than . At that point the curve becomes s = h (Fig. 2). 20), to increase as h −2 . When Re exceeds its critical value the averaged flow becomes turbulent. In the LES limit (near the origin in Fig. 22)) and when Re is large enough the turbulent LES fields approach Reindependence (Fig. 1). 9) for scalars. In the mesoscale limit the significant turbulent fluxes and mean-field gradients are those in the vertical, so the two closures are essentially equivalent.

P. , 1998; Caulfield and Peltier, 2000). The third transition occurs around Rλ = 900 starting at τ > 700: the “vertical” energy begins to grow (Fig. 3). This occurs without any evident accompanying growth in “wave” and “potential” energies, so it is something other than a gravity-wave outbreak. In fact it occurs in w at the largest vertical and horizontal scales in the domain. We have provisionally interpreted it as an example of a negative eddyviscosity instability, analogous to the result of Dubrulle and Frisch (1991) for a uniform-density flow, although this interpretation requires confirmation.
