| Zusammenfassung |
| The question of which length scale equation to use in models of
turbulence has long been controversial and several approaches have
been suggested and used in the past. In this paper, we demonstrate
that all these approaches are equivalent and the inconsistencies in
the use of some of these approaches arise from improper modeling of
the diffusion term in the length scale equation. We formulate a
general length scale equation, which encompasses all current
approaches. This equation is devoid of inconsistencies and should
prove useful in its general form, or one of its subsets, in
turbulence closure modeling. |
