✦ Synopsis

On the Stability of Falling Films-Periodic, Finite-Amplitude Waves

An analytical, theoretical investigation regarding periodic finiteamplitude (nonlinear) waves in a Newtonian, isothermal liquid film flowing along a vertical wall is presented. The periodic solution found provides full information regarding stability, wavelength, wave velocity, and wave amplitude as expressed exclusively in terms of physical constants and flow rate.
