摘要

An experimental investigation is described for the characteristics of convective boiling flow instabilities in horizontally helically coiled tubes using a steam-water two-phase closed circulation test loop at pressure from 0.5 MPa to 3.5 MPa. Three kinds of oscillation are reported: density waves; pressure drop excursions; thermal fluctuations. We describe their dependence on main system parameters such as system pressure, mass flowrate inlet subcooling, compressible volume and heat flux. Utilising the experimental data together with conservation constraints, a dimensionless correlation is proposed for the occurrence of density waves.
