Authors Lampropoulos N.K., Dimakopoulos Y., Tsamopoulos J. Abstract We study the transient, two-dimensional film flow over solid substrates with variable topography, a flow that has practical applications in microelectronics and microfluidics. The problem we address here is the advancing of a thin liquid film over square-shaped trenches with different depths […]

Authors Pavlidis M., Dimakopoulos Y., Tsamopoulos J. Abstract Two-dimensional, steady flow of a viscoelastic film over a periodic topography under the action of a body force is studied. The exponential Phan-Thien and Tanner (ePTT) constitutive model is used. The conservation equations are solved via the usual mixed finite element method […]
