Summary

An analytical model of stable subcooled flow film boiling on the front of a horizontal cylinder and a model for the wake region downstream of the flow separation points were developed. Heat transfer in the wake region can amount to up to 20% of the heat transfer in the forward region and should not be neglected, especially at high subcooling. The results of calculations are compared to experimental data. Experiments using R113 were conducted at subcooling levels up to 58 deg C and at velocities up to 3.81 meters per second. A method using a temperature correction to a constant-property heat transfer solution that corresponds to the full variable-property solution is also presented, and applied to water and R113.
