PROFESSIONAL EXPERIENCE

. Fluid-Solid Interaction (FSI) research of under water explosion near a

propeller: GEMINI coupled in use with DYNA3D in simulations; different

detonation amount, depth and angle positioning to the propeller were

simulated; composite material made propeller with different fiber

orientations and properties were investigated. Stress, defection and

failure were analyzed under different conditions, and optimum design

scheme was concluded.

. Erosion of materials due to cavitating flow: hybrid lattice particle

modeling (HLPM) code interfacing with bubble dynamics data was

developed. Potential application of this technique is a direct

solution to river bank erosion.

. Proposal writing, FSI code troubleshooting, enhancement and

development in FORTRAN, commercial software application, research

funding hunting, analysis and forecast, work presentation.

. Fracture of minerals under extreme loads (high-speed impact,

penetration, blast, fire)

Hybrid lattice particle modeling (HLPM) was developed as one of the

significant technique accomplishments for the DHS project "Nano-

Particle Reinforced Composites for Critical Infrastructure Protection"

($1,159,339). HLPM can accurately forecast on-site impact/penetration

experiments of polymeric materials (nylon6,6, vinyl ester, nano-

enforced materials); fire protection using nano-material inclusions

were investigated; retrofitting infrastructure with multi-layered

composite materials were modeled. 1 book chapter, 8 highly reputable

journal papers and 10 conference proceedings were published. Also,

commercial tools, AUTODYN and PFC2D, were in addition utilized.

. Loose sand foundation erosion due to plunging flow

FLOW3D was utilized for the fundamental investigation of New Orleans's

levee system failure during Katrina 2005 owing to its foundation

failure due to overtopping flow, belonging to the DHS project

"Structural, Material and Geotechnical Solutions to Levee & Floodwall

Construction & Retrofitting" ($1,959,537); different retrofitting

design using material blocks on the wall were simulated; optimum

scheme was obtained.1 journal paper and 1 conference paper was

published.

. Flooding forecast and assessment

NCCHE flooding code was developed with very thin structure considered.

GIS DEM terrain data employed.

. Course teaching: teaching and offering new courses to graduate

students.

. Proposal writing, management of proposal design, supervising junior

researchers.

. Dynamic fragmentation of materials (comminution, high-speed impact,

blast, etc.)

Thermal hybrid lattice particle modeling (HLPM) was developed and

applied to investigating thermally-induced fracture of rocks.

Fracturing rocks with microwave was modeled for visualizing, managing,

creating and analyzing for developing high-efficient fracturing

devices; valuable conclusions were drawn.

. Optimized computational efficiency.

. Developed research proposals.

. Atmospheric flow/pollutant transportation over a complex terrain

Los Alamos made code package, Higher Order Turbulence Model for

Atmospheric Circulation (HOTMAC) and Random Puff Transport and

Diffusion (RAPTAD), was applied to explore the complex atmospheric

flow evolution and therefore the driven pollutant dispersion in the

Great Phoenix valley area. 5 conference papers and 3 journal papers

were published as a result of this research. USGS terrain data and

landuse data were employed.

. Verified and validated regional meteorological model predictions and

analyzed dispersion results; performed parameter studies to

characterize systems.

. Applied simulation and visualization techniques to study physical

systems relate to pollution prediction.

. Attended one-week training of MM5 at NCAR, Boulder, CO.

. Atmospheric flow/pollutant transportation over a complex terrain

Higher Order Turbulence Model for Atmospheric Circulation (HOTMAC) and

Random Puff Transport and Diffusion (RAPTAD) was modified and applied

to explore the atmospheric flow in El Paso area. 2 journal papers and

2 conference papers were published as a result of this research.

Developed a 3D one-phase weakly compressible flow cavitation code;

Large Eddy Simulation (LES) scheme was employed; sheet and cloud

cavitation was well captured. The corresponding work was published on

times up to now.
