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.
