PROFESSIONAL EXPERIENCE

New Product Development

• Development of LED surgical light head. Both numerical simulation and experimental methods were utilized to

evaluate the thermal performance of electronic components inside the light head. Light head design was

optimized based on modeling and measurement results. Air flow over light head was also simulated to help

improve infection prevention.

• Development of next generation VHP (vaporized hydrogen peroxide) sterilizer. Computational model was built

to simulate multi-physics phenomena inside the sterilizer chamber such as multiphase flow, evaporation,

condensation and degradation etc to improve sterilization performance. Experiment was also conducted to

measure the sterilization efficacy. Innovative concepts were proposed for cycle development and tested both

computationally and experimentally.

• Development of VHP (vaporized hydrogen peroxide) BioSafety Cabinet Decontamination Unit. Computational

model was built to predict the VHP concentration distribution inside the cabinet under different conditions.

Complicated multi-physics phenomena were included such as multi-component flow, porous media flow,

condensation, adsorption, VHP decomposition etc. Simulation results were used to guide the mechanical design

of the unit and cycle development. Extensive experiments were conducted to test the unit performance and

determine the cycle parameters for different cabinets.

CFD Code Development

• Wrote a comprehensive 3D CFD code, BFH, which is specifically used by the steel industry to simulate hot

metal flow and heat transfer in commercial blast furnaces. This code can predict fluid flow through porous

media, conjugate heat transfer, multi-species transport, multi-phase flow and hearth refractory erosion pattern.

• Wrote a 3D CFD code to simulate electrophoresis and electroosmosis flows in microchannels. This code can

predict multi-species transport processes under the effect of electric field in MEMS (micro-electro-mechanical

systems) and microfluidic devices.

• Wrote a 2D axi-symmetric CFD code, ConeJet, to predict electrohydrodynamically driven capillary jet flows.

This code can calculate the free surface shape of the liquid flow, the velocity fields, the electric fields and the

surface charge density at the liquid-gas interface.

• Wrote a 3D parallel version of DSMC (direct simulation Monte Carlo) model using OpenMP on shared memory

super computers to predict micro-scale and low pressure gas flows. DSMC is a direct particle simulation

method based on kinetic theory. Dynamic domain decomposition can be performed to maintain a good load

balance among the processors in order to obtain maximum speed up.

Research Achievements

• Numerical investigation of effects of operating and design conditions on the blast furnace hearth. CFD code

was used to conduct a series of parametric studies to provide useful insights and guidance in monitoring and

controlling the hearth erosion process in a realistic industrial blast furnace hearth operation.

• Numerical simulation of PCI (pulverized coal injection) combustion in a blast furnace. The simulation involved

modeling interaction between continuous gas phase flow field and a discrete phase of coal particles. Coal

devolatilization and char combustion were modeled using non-premixed combustion model.

• Simulation of electro-kinetically driven capillary flows in microfluidic devices. Both electrophoresis and

electroosmosis phenomena were modeled. Flow field and species transport were simulated for loading and

dispensing processes to investigate species separation performance.

• Parallel processing using OpenMP, MPI (message passing interface), and C-Linda on distributed memory and

shared memory super computers. Parallels codes were optimized by reducing synchronization overhead due to

data contention and choosing proper granularity to maintain a good load balance among processors.

• Simulation of free surface flows in centrifuges using homogeneous multiphase model and VOF (volume of

fluid) model. The evolution of free surface along with the flow fields in both the gas and liquid phases were

analyzed in partially filled centrifuges.

• Simulation of electrohydrodynamically driven flows in the Cone-jet mode. Both Newtonian and Non-

Newtonian flows were considered. The effects of the voltage, surface tension, and flow rate on the free surface

flows were investigated.

• Simulation of micro-scale plasma discharges at atmospheric pressure using fluid model and PIC-MCC (particle-

in-cell Monte Carlo collision) method. The simulation included electron, ion and neutral particle transport.

Boltzmann equation was solved for the EEDF (electron energy distribution function) in order to calculate the

rates for electron induced chemical reactions. The atmospheric pressure plasma microdischarge can be used for

deposition of thin films and for microfabrication.

• Simulation of high Kn number gas flows and mixing in microchannels. The effects of the inlet velocities, the

inlet-outlet pressure difference, the pressure ratio of the incoming streams and the ‘accommodation coefficient’ of

the solid wall of the microchannel on the mixing behavior were examined.

• Simulation of low pressure gas flows in vacuum devices and molecular pumps. Ultimate pressure and

compression ratio were calculated for a wide range of Kn number flows with different speeds.

and wavelet networks were applied in the data training and prediction.
