• Effect of channel width on the primary instability of inclined film flow 

      Vlachogiannis, M.; Samandas, A.; Leontidis, V.; Bontozoglou, V. (2010)
      A procedure is developed to detect the onset of interfacial instability in inclined film flows (with estimated accuracy better than 5%) and is used to show that the finite width of experimental channels stabilizes the ...
    • Laminar film flow along a periodic wall 

      Bontozoglou, V. (2000)
      Laminar, gravity-driven flow of a liquid down an inclined wall with large-amplitude sinusoidal corrugations is studied numerically by a spectral spatial discretization method. The synchronous resonance between the wall and ...
    • Laminar film flow down a wavy incline 

      Bontozoglou, V.; Papapolymerou, G. (1997)
      Laminar how of a liquid, down an inclined wall with sinusoidal corrugations, is considered. A linear analysis, valid for small-amplitude disturbances but arbitrary wavelength and Re number, leads to an Orr-Sommerfeld type ...
    • 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 ...
