A Two-Dimensional Turbulent-Flow Mixing Model for Parallel-Flow Rod Bundles

A two-dimensional steady-state energy equation, in terms of the fluid enthalpy rise, for a nuclear reactor channel is formulated and solved. To facilitate its usefulness to the reactor designer, the solution is presented in the form of a hot-channel factor. Parametric results are presented so the information may be related to other channel dimensions. Mixing was found to be a function of the nondimensional geometry factor and the Peclet number.
