  • Experimental evidence for a short-wave global mode in film flow along periodic corrugations 

    Cao, Z.; Vlachogiannis, M.; Bontozoglou, V. (2013)
    The primary instability of liquid film flow along periodically corrugated substrates is studied experimentally. Two different wall shapes, of the same wavelength and height, are tested for a wide range of inclinations. It ...
  • Linear resonance in viscous films on inclined wavy planes 

    Wierschem, A.; Bontozoglou, V.; Heining, C.; Uecker, H.; Aksel, N. (2008)
    We study viscous gravity-driven films flowing over periodically undulated substrates. Linear analysis describes steady flow along small amplitude corrugations for films of arbitrary thickness. Solving the resulting system ...
  • Nonlinear resonance in viscous films on inclined wavy planes 

    Heining, C.; Bontozoglou, V.; Aksel, N.; Wierschem, A. (2009)
    We study nonlinear resonance in viscous gravity-driven films flowing over undulated substrates. Numerical solution of the full, steady Navier-Stokes equations is used to follow the emergence of the first few free-surface ...
