RELEVANT RESEARCH EXPERIENCE
1. Researches associated with ANSYS FLUENT® and ANSYS Workbench®
a. Contaminants transport in an indoor environmental chamber; (2010 ~ 2012)
    This project mainly concentrates on the spray effect, mixing procedure and transport of contaminants in a 3D room. The primary commercial packages involved are ANSYS FLUENT®, GAMBIT, ICEM-CFD, SolidWork® and FieldView®. Numerical models include turbulent models and multiphase flow models. The k-e, k-w, Reynolds Stress models and LES are investigated. Eventually, for the sake of achieving good convergence criteria and turbulent quantities, the standard k-e is chosen. In addition to species transport and discrete phase/parcel models, the user define scalar (UDS) is tested to consider the settling speed for the species transport.

b. Particle transport in a fully turbulent room with objects inside; (2012 ~ 2014)
This project mainly focuses on the boundary layer effect on the mixing procedure of the contaminants. Complicated 3D geometries are involved, i.e. a helicopter and humans. Siemens NX® is used to modify those geometries and the meshing module in the ANSYS Workbench® is adopted to handle the sophisticated geometry. Multiple turbulent models are tested and the RNG k-e one is finally selected acting as a low-Reynolds-number k-e model. The species transport model is used and the TecPlot 360® is for visualization.

c. Human thermal system and cooling process. (2008 ~ 2009)
    This project mainly concerns the heat transfer on the human body. A flow over cylinder with heat transfer was simulated with ANSYS FLUENT® in order to compare with results from experiments and an in-house immersed boundary method. The user defined function (UDF) of ANSYS FLUENT® is employed to define the non-uniformly isothermal wall boundary condition. In this project, I am committed to both numerical simulations and experiments.

d. Evolution of aircraft wake vortices. (2012)
This project mainly studies the decay of aircraft wake vortices in the vicinity of either a smooth or a rough ground. The UDF of ANSYS FLUENT® is utilized to initialize the velocity field.

e. Influence of atmosphere turbulence on wind turbine wakes;
    This project mainly investigates the influence of the atmosphere turbulence on the decay of wind turbine wakes. The UDF of ANSYS FLUENT® is employed to implement a helical vortex and few vortex rings in the initialization.

2. A parallel implementation of the immersed-boundary method and its applications on bio-inspired aerodynamics (Ph.D Thesis);
Parallel implementation of IB method with scientific library, PETSc, significantly speeds up the computational rate of the program. Applications involve following items:

a. Species transport  through porous media;
“Computation of flow through a three-dimensional periodic array of porous structures by a parallelized immersed-boundary method.”, Journal of Fluids Engineering (accepted)

b. Theoretical comprehensions of unsteady flow dynamics:
c. Vortex dynamics on downstream of flapping wings;
i. “Study of Mechanisms and Factors That Influence the Formation of Vortical Wake of a Heaving Airfoil”, Physics of Fluids, (2012)
ii. Mechanisms of Wake Deflection Angle Change behind a Heaving Airfoil", Journal of Fluids and Structures, (accepted)

d. Energy Harvesting of passive or active flapping airfoils;
“Energy harvesting of a flapping airfoil in a vortical wake”, AIAA Journal, (in preparation)
