FILM FLOW AND HEAT TRANSFER ON A VERTICALLY GROOVED SURFACE
Abstract
The horizontal profiles of gravity driven
liquid films flowing on vertically grooved
surfaces are evaluated for two cases. The first
case represents flow of relatively thin films over
grooves with relatively small periodicity and
amplitude. In the second case, the grooves are
relatively small, closely spaced. The flow is then
characterized by thick films which flow inside the
grooves and with eventual overflooding of the
grooves and the formation of a flat liquid interface.
Relatively simple calculation procedures are
proposed and some representative heat transfer
data are also presented.
