A new model of turbulence is proposed for the estimation of Reynolds stresses in turbulent fully-developed flow in a wall-bounded straight channel of an arbitrary shape. The main idea of a Multi-Scale Viscosity(MSV) model can be expressed in the following phenomenological rule:A local deformation of axial velocity can generate the turbulence with the intensity that keeps the value of the localturbulent Reynolds number below some critical one. Therefore,in MSV,the only empirical parameter is the critical Reynolds number. Since MSV can naturally predict turbulent viscosity anisotropy in directions normal and parallel to the wall,it is capable to calculate secondary flows in thecross-section of the rod bundle.
