Research Interests:

  1. Fictitious domain methods and its applications on particulate flow (the support of the NSF grants ECCS-9527123, CBET-9873236, DMS-9973318, DMS-0209066, DMS-0443826 and DMS-1418308 is acknowledged.).
    • Developping distributed Lagrange multiplier/fictitious domain (DLM/FD) methods for simulating particulate flow in Newtonian and non-Newtonian fluids, including suspensions, sedimentation, liquid-solid fluidized bed, slurry transportation, and etc..
    • Study properties of particulate flow via direct numerical simulations by distributed Lagrange multiplier/fictitious domain methods.
  2. Immersed boundary methods and its applications on blood flow (the support of the NSF grants DMS-0443826 and DMS-0914788 is acknowledged.):
    • Developping immersed boundary methods for simulating the red blood cell motion in blood flow.
  3. Computational fluid dynamics: Incompressible viscous flows and Viscoelastic fluid flows.
  4. Scientific computing, Numerical analysis.

Research on Particulate Flow and animinations:

  1. Sedimentation: balls, ellipsoids, truncated cylinders settling in an incompressible viscous Newtonian and non-Newtonian fluids.
  2. Suspensions and slurry transportation in non-Newtonian fluids.
  3. Pattern formation of non-Brownian settling balls in a rotating fluid-filled horizontal cylinder.
  4. Migration and orientation of a neutrally buoyant particle in 3D Poiseuille flows.
  5. Fluidization: 1204 ball fluidized bed, fluidization of 60 truncated cylinders.

Research on the motion of the red blood cells in microchannels and animinations:

  1. Blood cells move in a microchannel with/without a constriction.
  2. Many blood cells migrate in a Poiseuille's flow.
