Abstract
The bubbling process is experimentally investigated in two rod assemblies, namely, an 80-rod electrically heated assembly and a 40-rod adiabatic assem bly. The main forces and processes are treated which define the behavior of a two-phase mixture under given conditions. Calculated correlations are de rived for determining the true void fraction, the drift velocity, and the d istribution parameter in rod bundles.
