DESCRIPTION:Jae Sung Park\, Associate Professor Department of Mechanical a
 nd Materials Engineering  University of Nebraska-Lincoln\nThis seminar wi
 ll start by introducing diverse fluid-mechanics projects conducted in the 
 Park Research Group at Nebraska. I will then focus on two projects at very
  different Reynolds number regimes. For both projects\, the modeling\, ana
 lysis\, and computation will be presented along with their engineering app
 lications. The first part is dedicated to a high Reynolds number flow (tur
 bulent flow)\, where three flow-control methods\, namely adding polymers\,
  utilizing slippery surfaces\, and applying external forces\, are investig
 ated for skin-friction drag reduction. I will present their underlying mec
 hanisms of turbulent drag reduction. The second part is dedicated to a low
  Reynolds number flow (Stokes flow)\, where dynamics and rheology of condu
 ctive microparticle suspensions in an electric field are investigated. In 
 particular\, I will present rheology control for shear thinning\, shear th
 ickening\, and gel formation of such complex fluids via the magnitude and 
 frequency of the electric field.\n\nDr. Jae Sung Park is Richard L. McNeel
  Associate Professor of Engineering in the Department of Mechanical and Ma
 terials Engineering at the University of Nebraska-Lincoln (UNL). He receiv
 ed his B.S. from Hanyang University in 2006 and his M.S. and Ph.D. from th
 e University of Illinois at Urbana-Champaign in 2008 and 2012\, respective
 ly. All degrees are in Mechanical Engineering. Prior to coming to UNL in 2
 017\, Dr. Park was a postdoctoral researcher in the Department of Chemical
  and Biological Engineering at the University of Wisconsin-Madison from 20
 12 to 2016. His research encompasses a wide range of fluid mechanics from 
 small to large scales\, involving complex fluids\, rheology\, transition-t
 o-turbulence\, and turbulence. He has been awarded the UNL College of Engi
 neering New Faculty Teaching Award in 2020\, NSF CAREER Award in 2021\, UN
 L College of Engineering Research Excellence Award in 2023\, UNL Universit
 y-wide Teaching Award in 2024\, ASME Rising Stars of Mechanical Engineerin
 g in 2024\, and Best Presentation Award at KSME Annual Meeting–Internati
 onal Session in 2024.
