Abstract
The emphasis in this chapter is on averaged turbulence modeling in rod-bundles on an intermediate scale that is finer than the sub channel scale but much larger than the scale required for direct numerical simulation. Thirteen benchmarks based on analytical solutions and experimental data are presented and compared with the prediction of the IVA computer code. For the first time distribution of the averaged turbulence structure in boiling bundles is presented. It is demonstrated that k-eps models with two-way coupling possess substantial potential for increasing the accuracy of the description of multi-phase flow problems in bundles especially the effect of the space grids.
