Flame, Gone With Butterfly

Second Place Prize, 2010 Combustion Art Competition, the Combustion Institute, by Yanan Gan & Li Qiao, Purdue University

 

 “CH4/Air premixed flame attached to a carbon-coated brass matrix cooled with water. Fuel rich to fuel lean from left to right and top to bottom by increasing air flow rate and decreasing CH4 flow rate. Small flames dance around and a butterfly appears. When the butterfly flies away, flame is gone.”

Dr. Combustion

Second Place Prize, 2011 Combustion Art Competition, the Combustion Institute, by Bogdan Pavlov & Li Qiao, Purdue University

 

 “A family of methane-air counterflow and premixed flames of different configurations with and without addition of nanoparticles. Depending on flame configuration, the particles may pass reaction zone, be heated and irradiate light (nose, beard, and hair). In certain configurations of a counterflow diffusion flame, the reaction zone acts as a strong fluid-dynamics source and diverts the particles, making them not reach the reaction zone (eyes and mouth). A classical methane-air diffusion flame provides Dr. Combustion with an elegant hat as he cannot conceal the joy of discovery.”

Afrit (Arabian mythology) - The Fire Monster

 

Prize for Artistic Merit, 2015 Combustion Art Competition, the Combustion Institute, by Sayan Biswas & Li Qiao, Purdue Univeristy


“High speed schlieren photography of pre-chamber generated turbulent jet ignition of lean CH4/air - potential solution to ultra lean combustion. Devil's face is made of wrinkled turbulent flames. Horns are composed of two flame-jets from pre-chamber combustion. The hot puff on top of devil's head represents initiation of ignition in main combustion chamber. This image contains all three phases of prechamber generated jet ignition process, namely, the pre-chamber flame-jet, main chamber ignition point and flame propagation.”

Mesmerizing Micro-World of a Monopropellant Matrix (4M)

 

Honorable Mention, 2016 Combustion Art Competition, the Combustion Institute, by Sayan Biswas, Shourya Jain and Li Qiao, Purdue University


“Flame speed of a solid monopropellant (nitrocellulose) enhances up to 14 times the bulk value when coupled to a highly conductive thermal base (graphite sheet) at microscale. This image made of several Scanning Electron Microscope (SEM) images, shows three phases of the graphite base/matrix,

  1. Before adding monopropellant (inner rectangle)
  2. After adding monopropellant (intermediate rectangle)
  3. After monopropellant burns out (outer rectangle)”

 

 

 

Postdoc and PhD Positions Available at Purdue University

 

The School of Aeronautics & Astronautics and the School of Mechanical Engineering at Purdue University invite applications for one postdoc position and one phd position under the direction of Prof. Li Qiao.   https://engineering.purdue.edu/AAE/people/ptProfile?resource_id=39640   The research project is related to high-pressure injection processes that occur in most engines such as automobile engines, gas turbine engines and rockets. 

 

Requirements:

 

For the postdoc position, applicants must have a Ph.D degree in mechanical engineering, physics, chemistry, or a related field.  Extensive experience with molecular dynamics simulations is required. Familiar with molecular dynamics simulation softwares such as LAMMPS is required. Specialization in area of supercritical fluids is highly desired. The applicant must also have excellent written skills to publish scholarly papers.

 

For the PhD student, applicants must have a BS or MS degree in mechanical engineering, or a related field. Some background on molecular dynamics simulations or experimental fluid mechanics is preferred, however, not required. 

 

How to Apply:

 

Interested applicants should send a CV to Prof. Li Qiao (lqiao@purdue.edu). Contact information for at least three references should be included.
