The study of modern combustion and propulsion systems calls for innovative and effective experimental methods.  This seminar presentation will discuss several new laser diagnostics for flow and combustion imaging.  These diagnostics all evolve around the three-dimensional (3D) and high-speed imaging of chemically reactive flows.  It has been widely recognized that such diagnostic capability is solely needed to understand the complicated turbulence-chemical interactions, a long standing scientific problem with profound practical applications.  This presentation will focus specifically on two approaches to enable such diagnostic capability: multidimensional temperature and chemical species measurement using absorption and emission tomography.  These techniques are expected to enable instantaneous 3D imaging of key parameters with high temporal resolution, and provide experimental data long desired for the study of combustion and propulsion systems.

Biography:

Dr. Lin Ma received a B.S. in Thermal Engineering from the Tsinghua University in 2000, and M.S. and Ph.D. degrees in Mechanical Engineering from Stanford University in 2001 and 2006, respectively.  He started his academic career in 2006 after completing his Ph.D. work, focusing on multidimensional laser diagnostics.  His work on 2D mixture fraction measurement was recongized by the National Science Foundation with a CAREER award.  He is also active in teaching and professional services.  His teaching and research efforts were recognized by a Board of Trustee Award.  He is an AIAA associate fellow and an active technical committee member for several professional organizations.
