Abstract
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/(m2 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/(m2 s)), and in a wide range of variation of void fraction (0–1.0).
