LIQUID FILM FLOW

UDC 532.5

The results of investigation of the influence of a solid 
surface on the film flow of a viscous incompressible liquid in a gravitational 
field are analyzed. Using the dimensional method, a generalized similarity 
criterion for a film flow has been obtained. The laboratory facility 
and the method for investigating the film flow for various types of 
packing elements are described.
