Falling film flow along steep two-dimensional topography: The effect of inertia
Bontozoglou, V.; Serifi, K. (2008)Steady film flow along a vertical wall with isolated step changes is studied numerically for Reynolds numbers Re similar to O(10(-3)-10(2)) and capillary numbers Ca similar to O(10(-2)-10(1)). The lengthscale of free surface ... -
Nonlinear dynamics of inclined films under low-frequency forcing
Argyriadi, K.; Serifi, K.; Bontozoglou, V. (2004)The evolution of an inclined liquid film, subjected to regular inlet disturbances of small frequency, f, is studied experimentally and computationally. The fluorescence imaging method is used to quantitatively document ... -
Solitary waves on inclined films: their characteristics and the effects on wall shear stress
Tihon, J.; Serifi, K.; Argyriadi, K.; Bontozoglou, V. (2006)The properties of solitary waves, developing from inlet disturbances of controlled frequency along an inclined film flow, are systematically studied experimentally and computationally. Time-variations of film height and ... -
Transient flow and heat transfer phenomena in inclined wavy films
Serifi, K.; Malamataris, N. A.; Bontozoglou, V. (2004)A finite-element numerical scheme is used to study rigorously the flow of an inclined liquid film and the heat transfer from the constant-temperature wall. Regular inlet disturbances are predicted to evolve into periodic ...
