CFD Analysis of the Generation and Manipulation of Ferrofluid Droplets

Karampelas I.H., Gómez-Pastora J., Amiri V., Tarn M.D., Bringas E., Iles A., Pamme N., Furlani E.P., Ortiz I., Flow Science Inc., US

In recent years, there has been a significant increase of droplet-based microfluidic systems. This is mostly due to the advantages that such systems present such as chemical and bio-compatibility, the ability to perform a variety [...]

Optimization of continuous-flow magnetic bioseparators through CFD numerical models

González-Fernández C., Gómez-Pastora J., Karampelas I.H., Bringas E., Ortiz I., The Ohio State University, US

Continuous flow bioseparators allow magnetic particles that are properly functionalized so that they get attached to dangerous pathogens. Specifically, the unique properties of magnetic particles enable their separation from blood, after fulfilling their role of [...]

Magnetohydrodynamic Drop-on-Demand Droplet Formation and Coalescence

Sukhotskiy V., Karampelas I.H., Vishnoi P., Vader S., Vader Z., Vader S., Vader Z., Amiri Roodan V., Verma A., Garg G., Furlani E.P., University at Buffalo, US

In recent years there has been a meteoric rise in interest and research in the field of metal additive manufacturing in both academia and industry. Such processes represent an attractive alternative to more traditional metal [...]

Numerical modeling of the formation of dynamically configurable L2 lens in a microchannel

Gupta A., Kitting J., Karampelas I.H., Flow Science Inc., US

The aim of this presentation is to describe the numerical modeling of a dynamically reconfigurable liquid-core liquid-cladding (L2) lens in a microfluidic channel, followed by a quantitative validation against the experimental results [1]. The lens [...]

Gómez-Pastora J., Karampelas I.H., Alorabi A.Q., Tarn M.D., Bringas E., Iles A., Paunov V.N., Pamme N., Furlani E.P., Ortiz I., University of Cantabria, ES

The use of droplet-based microfluidic systems has increased in the last decade due to the advantages these systems present, such as compatibility with many chemical and biological reagents, capability of performing a variety of “digital [...]

Design of Magnetic Blood Cleansing Microdevices through experimentally validated CFD modeling

Gómez-Pastora J., González-Fernández C., Karampelas I.H., Bringas E., Furlani E.P., Oriiz I., Flow Science Inc., US

Continuous flow bioseparators allow magnetic particles that are properly functionalized so that they get attached to dangerous pathogens, to be easily captured in a buffer solution. Specifically, the unique properties of magnetic particles enable their [...]

Additive Manufacturing of Microfluidic Components via Wax Extrusion

Schneider P., Sukhotskiy V., Christie L., Siskar T., Karampelas I.H., Furlani E.P., Oh K.W., University at Buffalo's Sensors & MicroActuators Learning Lab (SMALL), US

Fused deposition modelling (FDM) has been extensively applied in the fields of rapid prototyping and 3D printing, but typically this technique has mostly been used for the fabrication of low melting point plastics. This paper [...]

Drop-on-Demand 3D Metal Printing

Karampelas I.H., Vader S., Vader Z., Vader S., Vader Z., Sukhotskiy V., Verma A., Garg G., Tong M., Furlani E.P., University at Buffalo, US

At present, most 3D metal printing applications involve metal powder sintering or melting under the influence of an external energy source such as a laser (e.g. Selective Laser Sintering (SLS) and Direct Metal Sintering (DMLS) [...]

Numerical Analysis of Acoustophoretic Discrete Particle Focusing in Microchannels

Karampelas I.H., Gómez-Pastora J., Cowan M.J., Bringas E., Ortiz I., Furlani E.P., Flow Science Inc., US

Acoustophoretic particle focusing is a modern and very attractive method of removing a variety of objects from solutions in a microfluidic channel [1]. The process is inherently general and can be readily extended for multiple [...]

CFD analysis of particle magnetophoresis in multiphase continuous-flow bioseparators

Gómez-Pastora J., Karampelas I.H., Bringas E., Furlani E.P., Ortiz I., University of Cantabria, ES

The use of magnetic particles has recently expanded for a process known as detoxification in which different toxins and microorganisms are captured from the bloodstream of septic patients. Magnetic particle-based detoxification has been successfully applied [...]
