Computational Heat Transfer and Two-phase Flow in Miniature Tubes

We will report on our recent advances made in predicting this class of flow, using the Level Set approach, in which we have incorporated phase-change capabilities, surface tension and triple-line dynamics models based on the [...]

Simulation of filling of microfluidic devices using a coarse-grained continuum contact angle model

Narayanan C., Lakehal D., ASCOMP, CH

We present a new dynamic contact angle model applied to the fillingproblem in microfluidic devices. The level-set method is used forinterface capture. Several attempts have been made in the past decades to model contact--line dynamics [...]

A Framework for Mask-Layout Synthesis Implementing a Level Set Method Simulator

Lee C.-Y., Antonsson E.K., California Institute of Technology, US

Recently, evolutionary methods have been developed to automate MEMS mask-layout synthesis [3]{[6]. These design synthesis methods are iterative searches in which each iteration consists of mask-layout modification, determination of etched shape via an arbitrary 3-D [...]

Numerical Simulations of Sputter Deposition and Etching in Trenches Using the Level Set Technique

O'Sullivan P.L., Baumann F.H., Gilmer G.H., Bell Laboratories, Lucent Technologies, US

We have performed 2D and quasi-3D numerical simulations of physical vapor deposition (PVD) into high aspect ratio trenches used for modern VLSI interconnects. The topographic evolution is modeled using (continuum) level set methods. The level [...]
