High Order Finite Element Solution of Elastohydrodynamic Lubrication Problems [PDF]
, 2006 In this thesis, a high-order finite element scheme, based upon the Discontinuous Galerkin (DG) method, is introduced to solve one- and two-dimensional Elastohydrodynamic Lubrication (EHL) problems (line contact and point contact). This thesis provides an

Contact-line deposits from multiple evaporating droplets [PDF]
Physical Review Fluids, 2021 Building on the recent theoretical work of Wray et al. [J. Fluid Mech. 884 , A45 (2020)] concerning the competitive diffusion-limited evaporation of multiple thin sessile droplets in proximity to each other, we obtain theoretical predictions for the ...

Water-Repellency and Anisotropic Wettability of Micro-Grooved Polymer Surfaces [PDF]
한국정밀공학회지, 2020 Superhydrophobicity and anisotropic wettability can be simultaneously achieved by simple groove pattern on a surface. To verify those characteristics experimentally, we fabricated the micro-grooved surfaces with four different groove widths.
