Experimental Investigation of Sooty Flames
at High Pressures
Hamidreza G. Darabkhani* & Dr.Yang Zhang**
Introduction:
Through the funding from EPSRC a unique high pressure
burner has been developed in the last four years under
supervision of Dr. Zhang that much potentials of this burner
are awaiting to be explored. The burner has two standard
quartz windows and two pure silicone windows which are
transparent to infrared spectrum and beyond it.
Objectives:
The proposed PhD work will investigate:
1-The flame’s properties at high pressures in the infrared
spectrum, where the emissions of CO2 and H2O will fall into.
2- Using imaging techniques to measure the temperature and
concentration of the soot at different pressures.
3- To cross-correlate the obtained data in order to gain unique
physical insights into the flame’s properties at high pressures
and sooty conditions.
High Pressure Burner
It is expected that significant understanding of combustion at high
pressures could be gained through this proposed PhD project.
Methods:
Direct Imaging by a novel arrangement of CCD Camera,
Monochromatic Filters, Optical Fibres and Two Colour IR
Pyrometer.
