Mathematical modeling of turbulent flows at small Reynolds numbers.

Author(s) : BRECHLING J.

Type of article: Article

Summary

Five mathematical models of turbulent flows are considered, and their results are compared mainly in terms of the calculated profiles of the averaged velocities. Models considering two-dimensional perturbations do not satisfactorily explain the development of the profile of a turbulent flow or the increase in flow resistance. Models involving considerations of the stability with respect to three-dimensional perturbations of flows already subject to two-dimensional perturbation lead to more interesting results, and show that prediction of at least the time-averaged properties of turbulent flows is possible.
