\u6982\u8981\uff1a Nonlinear dynamics of externally forced falling
\n thin liquid films is discussed in the framework
\n of a first-order weighted-residual integral
\n boundary-layer equations. The problems of (i) a
\n vertical tangentially oscillating planar and of
\n a corrugated periodic vertical wall are considered.
\n Both of these dynamics are analyzed analytically
\n and numerically in the framework of these equations.<\/p>\n
In problem (i) the set of evolution equations admits
\n a solution corresponding to a flat film with a temporally
\n periodic volumetric flow rate. Using Floquet theory
\n stability of this solution is investigated. In the
\n region of instability of time-periodic flow, forcing
\n of the traveling wave and non-stationary wave regimes
\n arising in the unmodulated system, results in the emergence
\n of quasiperiodic and apparently chaotic regimes, respectively.
\n The wave regimes of crest and depression types survive the
\n forcing imparted by plane oscillation. The existence of
\n regions of asymptotical stability of the flat film
\n with a temporally periodic flow rate provides the window
\n for reduction or even suppression of the waviness of the
\n film interface. Numerical investigation of the nonlinear
\n dynamics of the modulated film confirms the analytical
\n results arising from Floquet theory.<\/p>\n
In problem (ii) steady-state flows are found in the case
\n of an asymptotically small wall corrugation and their
\n stability is investigated. It is found that steady flow
\n regimes arise in the case of a relatively small wall
\n wavelength for the Reynolds number below its critical value
\n corresponding to the flat-wall flow and for larger amplitudes
\n of the wall corrugation when the Reynolds number exceeds its
\n critical value. In the case of a larger wall wavelength,
\n the emerging flows are genuinely nonstationary or time-periodic.
\n The temporal period of the time-periodic flows increases with the
\n amplitude of the wall corrugation and decreases with the
\n Reynolds number. A possibility of the emergence of reverse flows
\n in both problems is also discussed.<\/p>\n
