Random Vortex Method for Geometries with Unsolvable Schwarz-Christoffel Formula

In this research we have implemented the Random Vortex Method to calculate velocity fields of fluids inside open cavities in both turbulent and laminar flows. the Random Vortex Method is a CFD method (in both turbulent and laminar fields) which needs the Schwarz-Christoffel transformation formula to map the physical geometry into the upper half plane. In some complex geometries like the flow in...

Generation of dynamic chemical signals with microfluidic C-DACs.

The utilization of microfluidic "lab-on-a-chip" devices in fundamental medical research, drug discovery and clinical diagnostics has rapidly increased in the past decade. Lab-on-a-chip devices process small volumes of analytes and reagents through on-chip microfluidic signal processing circuits. This paper discusses the implementation of a basic microfluidic circuit block, the concentration dig...

PROPER GROUNDING OF ADCs , DACs , AND OTHER MIXED - SIGNAL ICs

Each PCB in the system should have at least one complete layer dedicated to the ground plane. Ideally, a double-sided board should have one side dedicated to ground and the other side for interconnections. In practice, this is not possible, since some of the ground plane will certainly have to be removed to allow for signal and power crossovers and vias. Nevertheless, as much area as possible s...
