Abstract
A numerical model of a turbulent single-phase coolant flowing in line through a reactor-type fuel bundle is described for the prediction of the turbulent heat transport characteristics of the fluid and the fuel element pressure drop. A modified two-dimensional form of the Buleev mixing length theory is used to solve the momentum equation for the subchannel average velocity distribution, and for the distribution of the radial and tangential eddy momentum diffusivity. The effect of the anisotropy of the eddy momentum diffusivity in the wall region- on the wall shear stress distribution is examined.
