Presentation Title: Clogging Microchannels with Micro Gel Particles Discipline: Mechanical Engineering School: Southwestern Indian Polytechnic Institute Presentation Type: Oral Presentation Abstract: Clogging Microchannels with Micro Gel Particles Joshua Begay, Southwestern Indian Polytechnic Institute

Major filtration companies would like to make better filters but can’t because clogging is not well understood. Filters work by preventing contaminates from entering through clogging. To make better filters, we must understand clogging. We use soft lithography to fabricate microfluidic devices in PDMS for making emulsion and microchannels that are used for clogging. Gel particles are made using a two phase micro emulsion process, and then polymerized. We then clog microchannels with these gel particles. We find that to create a clog, the needed number of poly dispersed gel particles are more than mono dispersed hard particles.
