Summary:
Falling liquid films have several engineering applications, and the study of these films is considered to
be 811 important and essential aspect. This work aims to present an extensive experimental investisation
and theoretical analysis to a gravity driven laminar sinusoidal falling watr-.r film over an inclined plate to
study its main ch81'3Cteristics such as: wave profile, mean wave thickness, wavelength and wave velocity.
Film characteristics ~ investigated for different inlet water flow rate an.j inclination angles to obtain the
relation of the wave flow characteri~1ics with the variables taken in the stucy. The results show that average
wave thickness increases with Reynolds number and al~ with the flow ~irection. Good agJeement was
obtained between the experimental data and the theoretical results. Also, :he results agreed well with the
results or previous invest.igstions.
