By using a high speed camera

the bubble growth-condensation behavior under subcooled flow boiling in an inclined single-side heated rectangular channel was investigated experimentally.The influences of inclination angle on growth-condensation rate of bubbles

their distribution

maximum diameter and growth time were discussed.The results show that with same inlet parameters

the bubble maximum size and lifetime are proportional to the inclination angle; for different angles

the bubble size and growth time follow the 0.5 power law.In dimensionless form of Zuber model

in the growth region

the growth rate increases with increasing angle

but in the condensation region

there is no obvious relationship between the condensation rate and inclination angles.
