Dr. R.H. Chen now is working in University of Central Florida, USA as a full professor. By the invitation of Prof. X.L.Wei, Prof. R.H.Chen visited Institute of Mechanics, and gave a speech entitled ‘lift-off phenomena of Laminar Diffusion Flame with Dilution’ on July 30, 2010. Prof. R.H.Chen presented the new results on the relationship of laminar diffusion flame stability and Sc numbers. The results suggest that there was no suitable Sc number criterion as proposed by previous cold flow similarity analyses. Reaction flow results also indicate that the stabilization point is not necessarily where the local flame propagation matches the flame speed.
After speech, Prof. R.H.Chen visited CPCR’s laboratories, and discussed combustion relevant issues with Prof. H.Z. Sheng, Prof. X.L.Wei and other CPCR members.
