Here, a theoretical and numerical study is undertaken in order to understand the propagation of interfacial and surface waves in a two-layer flow down a vertical wall.</span></p>
<p style="font-weight: normal; font-family: 'Times New Roman'; -webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;">In this work, the mathematical modeling of a two-layer film flow using an approximate long-wave model is studied. The governing system is formulated as a dynamical system in order to calculate bifurcating families of steady-traveling nonlinear periodic waves.</p>

<p style="font-weight: normal; font-family: 'Times New Roman'; -webkit-text-stroke-color: rgb(0, 0, 0); -webkit-text-stroke-width: initial;">For different wavy regimes, absorption of a weakly soluble gas by the film is calculated. Systematic computations have demonstrated that the absorption rate strongly depends on a wave regime. This theoretical result can be used to enhance efficiency of real-life technological processes in chemical engineering, bioengineering and pharmaceutical industry. </p><p style="font-weight: normal; font-size: 12pt; font-family: 'times new roman', 'new york', times, serif;"><br></p>
