Abstract

Chapter 9 is devoted to the basics of designing of moisture separation. First the importance of knowing the characteristic spectra of the moisture is underlined for proper analysis. Then some simple methods for computation of the efficiency of the separation are given for cyclone type and vane type. Different ideas based on different complexity are presented for description of the velocity field: the Kreith and Sonju solution for the decay of turbulent swirl in pipes; the potential gas flow in vanes; description of the trajectory of particles in a known continuum field; the computational fluid dynamics (CFD) analyses of cyclones; the CFD analyses of vane separators. Then several experiments are collected from the literature for boiling-water reactor cyclones, pressurized-water reactor steam generator cyclones, other cyclone types, and vane dryers. In several cases the success of different methods is demonstrated by comparisons with data.
