Research Assistant

Sep. 2003 - Sep. 2009

( Independently conducted experimental and numerical studies on the

mechanism of the lean premixed combustion instabilities using

hydrocarbon fuels premixed with air or oxygen-helium in the

Variable Pressure Combustion Facility (VPCF) which can be used to

improve the design of lean burn engines to optimize the energy

efficiency and reduce emissions (Funded by NASA).

Designed and fabricated the VPCF which is composed of a liquid fuel

vaporization system, a high speed imaging system, and several

control systems to control pressure, temperature and mass flow.

Operated the variable pressure combustion tests, detected and

recorded the transient spiral and target flame instability patterns

using high speed video camera (up to 1000 fps), analyzed flame

dynamics using multiple image processing methods and developed

flame instability diagrams for various fuels, explored the roles of

diffusive fluxes of heat and species, density ratio, mixture

stoichoimetry, pressure and heat loss.

Expanded a 3D mathematical model including energy and mass balance

equations based on the experimental data to explore the mechanisms

of high-Lewis number lean premixed flame instabilities as a

function of fuel stoichoimetry, Lewis number, initial temperature

and heat loss using commercial CFD modeling software (Comsol

Multiphysics & Fluent).

( Managed experimental and numerical studies on the enhanced

combustion using nanocatalytic platinum particles with methanol/air

and ethanol/air (biofuel) mixtures at room temperature to explore

the potential applications with energy-efficient catalytic

micro-combustors and fuel cells (Funded by NSF).

Conducted the flow reactor experiments to elucidate the effects of

particle size, mass loading and gas flow rate on the reactivity of

the nano-size platinum catalytic particles with small alcohols.

Quantified the combustion reactants, intermediates and products

using Gas Chromatography (GC) to confirm complete combustion.

Performed gas & surface phase chemical process modeling for

methanol-air on nano-size platinum particles using chemistry

kinetics solver (CHEMKIN).

Supervised three undergraduate students in the Hess Undergraduate

Fellowship Program during various phases of this project.

( Actively involved in the hydrogen production project from methane

partial oxidation at low and intermediate temperature to seek

non-catalytic hydrogen production methods to support fuel cell

technologies and hydrogen-based economy.

Built a ceramic plug flow tube reactor to conduct preliminary

experimental research on optimal conditions (mixture compositions,

stoichiometries, pressures, temperatures, and residence times) for

hydrogen generation from methane partial oxidation.

Conducted a 1D CHEMKIN plug flow computation to show the conversion

of methane-air to hydrogen by partial oxidation at different

stoichiometries and temperatures.

Teaching Assistant

Sep. 2003 - July 2009

( Instructed the freshman engineering design class where freshmen

expand their understanding of different engineering disciplines,

gain basic engineering hands-on experiences, and learn to

communicate technical information.

( Assisted teaching several undergraduate and graduate classes of

Mechanical Engineering Department, e.g. Fundamentals of Fluid

Mechanics, Fundamentals of Aerodynamics, and Advanced Engineering

Analysis.

Research Assistant

Sep. 2000 - March 2003

( Studied systematically the desulfurization mechanism during coal

combustion at high temperature (Funded by Key National Fundamental

Research Project).

Characterized a variety of sulfur-removal additives such as

industrial wastes and minerals using XRD, SEM and mercury

Porosimetry before and after the sulfur removal reaction of coal

combustion.

Analyzed the effects of temperature and pressure on the kinetics of

sulfur-removal process with different coals based on the analysis

of weight loss using the plug flow reactor.

Explored the effect of reaction temperature, retention time,

compound composition, selection of additives on the formation of

high temperature phase of sulphoaluminate during coal combustion.

( Participated in a beta-site industrial experiment of limestone

injection desulfurization in a pulverized coal-fired boiler.

Responsible for the fire temperature measurement, the flu gas

analysis and the sulfur-removal efficiency calculations.

( Internship at Zhejiang Provincial Electric Power Design Institute

in Hangzhou, China. Designed gas turbines and power plant boilers.
