Numerical Simulation of Droplet Shapes on Rough Surfaces

Patankar N.A., Chen Y., Northwestern University, US

It has been demonstrated that surface roughness causes superhydrophobicity. Our objective is to develop a numerical tool and study the relationship between the roughness characteristics and the apparent contact angle and motion of liquid drops [...]

Electroosmotic Flow and Zone Broadening in Microfluidic Channels of Variable Cross-Section and Wall Charge

Ghosal S., Lu Z., Northwestern University, US

Electroosmotic flow is often the method of choice for generating fluid flows in micro fluidic devices. The resulting flow has a characteristic at profile which has the advantage of very low axial dispersion. This is [...]

Direct Numerical Simulation of Moving Charged, Flexible Bodies with Thermal Fluctuations

Patankar N.A., Northwestern University, US

The interaction of sub-micron scale objects with fluids is an important problem encountered in miniaturized systems. Various physical phenomena should be modeled simultaneously for a fundamental investigation of these systems. Our objective is to develop [...]

3-D Computational Modeling of RF MEMS Switches

Espinosa H.D., Fischer M., Zhu Y., Lee S., Northwestern University, US

Young's modulus and residual stress state of freestanding thin membranes are characterized in this work by means of wafer level experimental techniques. RF MEMS Switches manufactured by Raytheon Systems Co. are investigated using a new [...]
