Hydrodynamic drag of a flow of steam-water mixture in a pebble bed
Annotation
Analysis is performed of the effect of the basic process parameters on the pressure loss under conditions of two-phase flow in a pebble bed. Relations are suggested, which generalize the available data of experiments involving steam-water flows in pebble beds (the ranges of variation of pressure from $0.9$ to $15$.6 MPa, of mass velocity in the pebble bed from $180$ to $770$ kg/(m$^2$ s), and of steam quality from zero to $0.48$), as well as the data for porous structures of sintered spherical bronze particles of small diameter ($0.16$—$0.63$ mm) at relatively low pressures ($0.2$—$0.59$ MPa) and low mass velocities ($10$ to $27$ kg/(m$^2$ s)), and in a wide range of variation of void fraction ($0$—$1.0$).
