Background

Wenting Sun received his B.E. and M.E. degrees in Engineering Physics from Tsinghua University, Beijing where his studies focused on non-equilibrium plasmas. After that, he graduated from Princeton University, department of mechanical and aerospace engineering working on plasma assisted combustion and combustion kinetics. Shortly after graduation, he joined Georgia Tech in 2013. His primary research interests lie in a broad range of reacting flows (combustion & plasmas) and propulsion systems. His current research activities involve plasma assisted combustion, chemical kinetics of different fuels, and laser diagnostics and spectroscopy of reacting flow systems.

Research

Dr. Wenting Sun’s research interest lies in a broad range of reacting flow system. His current research spans on:

(1) Plasma Assisted Combustion:

Owing to its unique capability to produce reactive species and heat, plasma (electrical discharge) is a promising way to modify the dynamics and reaction pathways of combustion to reduce emissions, improve engine performance, and achieve high-speed air-breathing propulsion. It will also lead to the new technologies for future novel combustors. In this topic, the research focus is to investigate the coupling of plasma kinetics and fuel oxidation and this kinetic process on the effect of flame dynamics.

(2) Advanced Diagnostics for Fossil and Renewable Fuels Combustion:

With the increasing concerns of energy sustainability and renewability, clean combustion and combustion with renewable fuels become to be more and more challenging. To overcome these challenges, it is critical to understand the combustion kinetics of both fossil and renewable fuels. Different techniques, such as laser diagnostic and spectroscopy, molecular beam mass spectrometry, are going to be developed and employed to study the kinetic process in combustion systems including trace species detection, pollutant formation and so on. This topic is very multi-disciplinary requiring knowledge of applied physics, laser spectroscopy, and chemical kinetics and can be extended to upper atmosphere and environmental research.

(3) Nano-scale Energy Conversion and Synthesis of Functional Materials:

The properties of nano-materials can be engineered by tuning synthesis conditions such as temperature, pressure, residence time, precursors, and concentrations of different species. Both combustion and plasma provide controllable ways (oxidation and non-oxidation) to engineer and mass produce new functional materials. The focus of this topic is to develop combustion/plasma coupled synthesis methods for nano-materials for clean energy.
