Non-premixed lifted flame stabilized in the IIST-GS1 swirl burner
Vortex structures produced in a laminar nozzle burner; Diagnostic technique : Mie scattering
The Flame Diagnostics Lab set up in the Department of Aerospace Engineering at IIST is an experimental test facility for combustion diagnostics in subscale and standard burner flames at atmospheric conditions.
In addition to the implementation of the conventional measurement techniques, the lab also facilitates employment of state of the art optical and laser diagnostic measurement techniques to combustion studies.
The lab can be used for development of advanced combustion and propulsion systems as well as for fundamental R&D in gaseous and liquid fuel systems.
Current research focuses mainly on turbulent gaseous and liquid fuel flames and development of standard burners and injectors for combustion/propulsion applications
Atomization process with increasing gas-to-liquid (GTL) ratio in an aerated injector.
Diagnostic technique: Shadowgraphy
Some of the measurement techniques that can be realised in this lab are:
Schlieren/Shadowgraph – density gradient visualization, atomization pattern between isothermal and reactive flow conditions
Optical Spray Diagnostics – drop size and velocity, planar velocity field measurements (both isothermal and reactive flow fields) – characterizing the velocity field
High-speed Flame Luminosity – dynamic event capture
Flame Chemiluminescence – size and shape of the heat release zone
Particle Image Velocimetry (PIV) - 2D flow field distribution
Planar Laser Induced Fluorescence (PLIF) - measurements of flame radicals, reactive species imaging and mixing studies,
Pollutant emission measurements
Simultaneous diagnostic measurements.
