...H. Ait Abderrahmane; G. H. Vatistas This technical brief deals with the surface instability mode of a liquid film flowing down an inclined plane. A four-equation model that describes the development of the film depth, the flow rate, the free-surface velocity, and the wall shear stress is proposed...

... c 2 and decays for k 2 < k c 2 . Furthermore, the results show that the effect of the magnetic field is to enhance the stability of a thin nonuniform conducting film flow on a spinning disk. Although the amplitude of the disturbance is larger for M = 2 than M...

...-based range of Re δ ⩾ 30 . The wave effects due to film flow’s sensitivity to ever-present minuscule transverse vibrations of the condensing surface are also described. The results suggest some ways of choosing wall noise—through suitable actuators—that can enhance or dampen wave fluctuations and thus...
