BX-16 Crossflow Boiling of Fluids with Noncondensable Gas

L. Huang

HTRI used an ideal inline plain tube bundle to collect crossflow boiling data for fluids with noncondensable gas. Using these data, we improved the predictions of the vapor-phase coefficient at the liquid-vapor interface and the convective boiling mixture correction factor in our crossflow boiling model. For cases with a large amount of noncondensable gas, the proposed method predicts up to 70% lower vapor-phase resistance. Convective boiling requires less mixture correction in the shear-controlled regime, but more in the gravity-controlled regime.
