Description
  • The characteristics of lead-bismuth(Pb-Bi)-water boiling two-phase flow were investigated experimentally and analytically using a Pb-Bi-water direct contact boiling two-phase flow loop. Pb-Bi flow rates and void fraction were measured in a vertical circular tube at conditions of system pressure 7MPa, liquid metal temperature 460°C and injected water temperature 220°C. The drift-flux model with the assumption that bubble sizes were dependent on the fluid surface tension and the density ratio of Pb-Bi to steam-water mixture was chosen and modified by the best fit to the measured void fraction. Pb-Bi flow rates were analytically estimated using balance condition between buoyancy force and pressure losses, where the buoyancy force was calculated from void fraction estimated using the modified drift-flux model. The deviation of the analytical results of the flow rates from the experimental ones was less than 10%.

  • Vlastnosti dvoufázového prodění s přímým varem směsi olovo-vizmutu a vody byly zkoumány experimentálně a analyticky za použití smyčky pro přímý var vody v olovo-vizmutové lázni. Hmotnostní průtok olovo-vizmutu a objemový podíl páry byly měřeny ve svislé trubce kruhového průřezu při 7MPa, teplotě olovo-vizmutu 460°C a teplotě vstřikované vody 220°C. Pro modelování byl zvolen drift-flux model s předpokladem, že velikost bublin je závislá na povrchovém napětí a poměru hustot olovo-vizmutu a vody. Model byl modifikován podle naměřených dat objemového podílu páry. Hmotnostní toky olovo-vizmutu byly analyticky určeny pomocí bilancování tlakových ztrát a vztlakové síly, která byla určena z objemového podílu páry vypočteného pomocí modifikovaného drift-flux modelu. Odchylka analytických výsledků hmotnostních toků od naměřených hodnot byla méně než 10%. (cs)
