Efficiency and Accuracy Improvements for FastStokes, A Precorrected-FFT Accelerated 3-D Stokes Solver
In this paper we present several efficiency and accuracy improvement to the precorrected-FFT accelerated Stokes flow solver, FastStokes. Accuracy was improved by deriving analytical formulas for required integrals of Stokes equation Green sfunctions, cpu time [...]
Scaling Issues for Calculations of Low-Velocity Gaseous Microflows
Gaseous flows in microfluidic devices are often characterized by relatively high Knudsen numbers, Kn. For such flows, the continuum approximation is not valid, and Direct Simulation Monte Carlo (DSMC) is an appropriate solution method. However, [...]
Dynamics in Microfluidic Systems with Microheaters
The physics of nucleation, boiling, bubble growth and collapse in thermal microactuators will be presented. The boiling process exhibits an equivalence to a phase transition of second order and this leads, in contrast to classical [...]
Lubrication Analysis and Boundary Integral Simulations of a Viscous Micropump
Several recent papers discuss a novel viscous micropump consisting of Poiseuille flow of fluid between two plates and a cylinder placed along the gap perpendicular to the ow direction. If the cylinder is not centered, [...]
A Fast 3D Solver for Unsteady Stokes Flow with Applications to Micro-Electro-Mechanical Systems
In this paper we describe the extensions made to FastStokes, a precorrected-FFT accelerated stady Stokes solver, to solve the unsteady Stokes equation. We demonstrate the accuracy of the numerical approach by comparing computed results to [...]
Simulation of Electroosmosis Using a Meshless Finite Point Method
A Finite Point Method (FPM) based on a weighted least squares interpolation is presented for the simulation of electroosmotic transport in capillaries. This method requires no mesh and involves no Galerkin-type integration, making it more [...]
A Passive Fluid Valve Element for a High-Density Chemical Synthesis Machine
We have developed a passive valve element for use in a high-density chemical synthesis machine. The element stops fluid flow by the surface tension forces occurring at small channel openings. The openings are circular holes [...]
Stability Criterion for Microscale Concentric Flow of Two Immiscible Liquids
This paper addresses the establishment of a stability criterion for isothermal laminar concentric flow of two immiscible liquids. Using the approach of combined non-dimensional group anlysis and numerical simulations, it is established that the inner [...]
