CRUZ, D.O.A; BATISTA, F.N.  and  BORTOLUS, M.. A law of the wall formulation for recirculating flows. J. Braz. Soc. Mech. Sci. [online]. 2000, vol.22, n.1, pp.43-51. ISSN 0100-7386.

This work presents a new law of the wall formulation for recirculating turbulent flows. An alternative expression for the internal length which can be applied in the separated region is also presented. The formulation is implemented in a numerical code which solves the k-e model through a finite volume method. The theoretical results are compared with the experimental data of Vogel and Eaton (J. of Heat Transfer, Transactions of ASME, vol.107, pp. 922-929, 1985). The paper shows that the present formulation furnishes better results than the standard k-e formulation.

Keywords : Turbulence; recirculating flows; law of the wall.
