Measurements of (1) burn-out, (2) circumferential film flow distribution, and (3) pressure drop in a 17 × 27.2 × 3500 mm concentric and eccentric annulus geometry are presented. The eccentric displacement was varied between 0 and 3 mm. The working fluid was water. Burn-out curves at 70 bar are presented for mass velocities between 500 and 1500 kg/m2s and for inlet subcoolings of 10°C and 100°C. The film flow measurements correspond to the steam qualities χ = 19 % and 24 % for the mass velocity G = 602 kg/m2s and χ = 20 % and 23 % for G = 1200 kg/m2s. The influence of the circumferential rod film flow variation on burn-out is discussed.
