LOW-REYNOLDS k-ε MODEL OF TURBULENCE

ABSTRACT

A low-Reynolds k-ε model of turbulence with model functions not containing a spatial coordinate similar to y+ as an argument (this coordinate is usually used to correctly model turbulence near walls) is suggested. The model which is tried out on the developed flow of an incompressible fluid in a plane channel describes the laminar-to-turbulent flow transition correctly. The obtained coefficients of resistance obey the known Dean and Zarbi-Reynolds laws. Mean-velocity distributions virtually coincide with those calculated by the three-layer Karman model.
