Dr. Fang’s long-term goal is to improve the environment and reduce our energy needs by the advancement of clean combustion. He is interested in combustion, internal combustion engines, exhaust emissions and air pollution control, alternative fuels, spray and atomization, droplet impact, laser diagnostics for reacting flows, energy conversion systems, heat and mass transfer, and fluid mechanics.

Dr. Fang, who arrived at NC State in 2007, has developed a new graduate class in Advanced Engine Combustion (MAE 589), which was expanded to Automotive Power Systems (MAE589) recently. At the undergraduate level, Dr. Fang teaches Fluid Mechanics I (MAE 308) and Internal Combustion Engines (MAE 408). In his undergraduate classes Dr. Fang is known to bring to class a lot of videos that help students see flow and combustion behavior in action.

Dr. Fang’s research is interesting to students because it addresses important societal needs, the work is hands-on, and because the students design their own experimental apparatuses. The students particularly enjoy the high-speed cameras and the laser diagnostic methods that enable them to see inside the engine and observe the behavior of the combusting flame, suggesting how the combustion processes can be made cleaner.

Dr. Fang looks for students who are hard-working and creative. In return, Dr. Fang is an advisor who sets clear goals, works closely with his students in the lab and provides them with regular feedback.

Research Description

Dr. Fang is presently 1) studying engine spray atomization and combustion of liquid fuels, 2) performing fundamental work in understanding liquid break-up in two-phase flows, and 3) investigating liquid droplet interaction with complex surfaces, including fabrics, for Blood Pattern Analysis (BPA) in forensic science applications. Many of his advancements result from his unique strategies for the visualization of the fluid/combustion process. Within MAE, he collaborates with Dr. Buckner, Dr. Edwards, Dr. Ngaile, Dr. Jiang, and Dr. Zhu.
