Microfluidic Simulation of a Separation System of T.cruzi from Blood Samples

S. L. Florez [1], M. J. Noguera [1], A. L. Campaña [1], J. C. Cruz [1], J. F. Osma [2],
[1] Department of Biomedical Engineering, University of Los Andes, Bogotá, Colombia
[2] Department of Electrical and Electronics Engineering, Microelectronics Center, University of Los Andes, Bogotá, Colombia

In 2014, it was estimated that there are between 6 to 7 million people worldwide infected by Chagas disease and approximately 25 million people are currently at risk. The parasite Trypanosoma cruzi (T. cruzi) causes this disease and according to the World Health Organization (WHO) it can ... Read More

Increasing Heat Transfer in Microchannels with Surface Acoustic Waves

S. Berry[1]
[1]Massachusetts Institute of Technology: Lincoln Laboratory, Lexington, MA, USA

In this numerical study, surface acoustic waves (SAWs) are evaluated as a potential disruptive flow technology for enhancing heat transfer in microchannels. Using COMSOL Multiphysics® software, the physics governing acoustics, single-phase-fluid flow and heat transfer are coupled. The ... Read More
