ABSTRAKT

The heat transfer mechanism of a liquid film flowing down horizontal tubes is studied by experimental determination of local and average heat transfer coefficients. A method of its enhancement is developed which is based on the break-down of the heat boundary layer by longitudinal fins and grooves. The calculated functions and recommendations on geometrical parameters of profiling, which allow heat transfer enhancement by a factor of 1.4−1.9 and overall “vapor-liquid” heat transfer by a factor of 1.3−1.5, are given.
