    • Animation of boiling phenomena 

      Bülbül, Abdullah; Küçüktunç, Onur; Özgüç, Bülent (IEEE, 2008-05)
      Phenomenon of boiling is a challenging topic for computer graphics due to its complex hydrodynamics and formulation. Realistic fluid animations require very heavy three-dimensional fluid flow calculations, and surface ...
    • Homogenization of soft interfaces in time-dependent hydrodynamic lubrication 

      Kabacaoğlu, G.; Temizer, İ. (Springer Verlag, 2015)
      The difficulty behind the unsteady lubrication problem is the oscillation of the film thickness in both position and time. The present study aims to extend the multiscale analysis of lubricated interfaces to the unsteady ...
    • Homogenization-based design of surface textures in hydrodynamic lubrication 

      Waseem, A.; Temizer, İ.; Kato, J.; Terada, K. (John Wiley and Sons Ltd, 2016)
      An optimization framework is developed for surface texture design in hydrodynamic lubrication. The microscopic model of the lubrication interface is based on the Reynolds equation, and the macroscopic response is characterized ...
    • Linear and nonlinear stability of a quasigeostrophic mixing layer subject to a uniform background shear 

      Biancofiore, Luca; Umurhan, O. M. (American Physical Society, 2019)
      The aim of this work is to shed light by revisiting, from the kernel-wave (KW) perspective, the breakdown of a quasigeostrophic (QG) mixing layer (or vortex strip or filament) in atmosphere under the influence of a background ...
    • A simple approach for the fabrication of 3D microelectrodes for impedimetric sensing 

      Guler, M. T.; Bilican, I.; Agan, S.; Elbuken, C. (Institute of Physics Publishing, 2015)
      In this paper, we present a very simple method to fabricate three-dimensional (3D) microelectrodes integrated with microfluidic devices. We form the electrodes by etching a microwire placed across a microchannel. For precise ...
    • Solid or liquid? Solidification of a nanoconfined liquid under nonequilibrium conditions 

      Patil, S.; Matei, G.; Oral, A.; Hoffmann, P. M. (American Chemical Society, 2006)
      There has been a long-standing debate about the physical state and possible phase transformations of confined liquids. In this report, we show that a model-confined liquid can behave both as a Newtonian liquid with very ...
    • Surface wave splitter based on metallic gratings with sub-wavelength aperture 

      Caglayan H.; Özbay, Ekmel (Optical Society of American (OSA), 2008)
      We investigated the splitting of surface electromagnetic waves trapped at the output surface of a one-dimensional metallic grating structure. The output gratings of the structure asymmetrically such that the output surfaces ...
