Optical diagnostics in reactive flows

 

  • Different sectors such as rocket engines, gas turbines, IC engines, coal gasifiers, industrial burners for nanoparticles generation etc. involve spray combustion process.

  • Hence, it is important to perform various measurements and investigations in the combusting/reactive flow environment.

  • Nanoparticle generation through coaxial airblast atomization.

  • Non-intrusive optical diagnostic techniques used: (a) Particle Image Velocimetry (PIV) for investigating the velocity of the spray droplets in the absence and presence of flame, (b) Two-dimensional Multi-Angle Light Scattering ( 2D-MALS) to investigate the size of nanoparticles generated after spray combustion.
