Abstract:This article investigates the stability of a thin power-law liquid film flowing down along the outside surface of a rotating vertical cylinder. The result is improved through the introduction of the flow index and the rotating centrifugal force into the governing equation. In contrast to most previous studies presented in the literature, the solution scheme employed in this study is based on a power series approximation approach rather than an analytical method. The growth rate of the amplitudes, the wave spee… Show more
