  Two- and three-dimensional waves in falling film flow in the nonlaminar flow regime: an NMR study

  摘要：

  Nuclear magnetic resonance (NMR) velocity-encoded imaging results as well as propagators are presented for the nonlaminar flow regime of falling films. The film is generated by a continuous flow of silicon oil along a vertical poly(methyl methacrylate) plate. While the film remains purely laminar for a film Reynolds number Re-f = 0.5, it exhibits laminar-wavy behavior for 1.0 less than or equal to Re-f less than or equal to 2.5. In this range, a laminar residual film can be distinguished from averaged waves near the surface of the film from measurements of the flow velocity v(z) along the direction of gravity as a function of the coordinate x normal to the plate. The perpendicular velocity components v(x) and v(y) are zero within the accuracy of the measurement, indicating that the wave motion is two-dimensional in the laminar-wavy case. For higher Re-f the waves are found to be three-dimensional, a straightforward division into a residual film and waves in v(z) is lost and the waves extend over the whole thickness of the film.
