1. Title : Unsteadystreaming flow based TENG using hydrophobic film tube with different chargeaffinity 2. Speaker :JeeHwan Ahn(Advisor : Prof. Kyoung Kwan Ahn) 3. Date & Time : Wednesday, July 29, 2020, 2 pm 4. Venue :Room 409, Building 2 5. Abstract This research proposes a simple, eco-friendly and economical fluid-basedtriboelectric nanogenerator (Flu-TENG), which is based on polyvinylidenefluoride (PVDF) between elastomeric tubes (P-TENG) and biaxially orientedpolypropylene (BOPP) between elastomeric tubes (B-TENG). We examined theinteractions based on the relation between the hydrodynamics of pipe flow andelectrostatic induction at the electrical double layer (EDL). This is the firststudy to focus on the hydrodynamics of the unsteady pipe flow. From theexperimental results, it was verified that the peak to peak current fromunsteady flow is 70 times higher than that of steady flow. This provides a newapproach for improving the output power of the FluTENG for special applications. 6. Contact : Prof. Doo-Man Chun(☏052-259-2706) |
