Simultaneous measurement of scalar dissipation and flame orientation Conference Paper uri icon

abstract

  • An experimental system that combines multiscalar line imaging with OH PLIF imaging in two intersecting planes was presented. The technique provided measurements of OH mass traction along the one-dimensional line, and allowed determination of the local and instantaneous flame orientation and curvature. This, in turn, could be used to estimate scalar dissipation in the flame-normal direction, such that the instantaneous effects of scalar dissipation on compositional structure may be evaluated more accurately and the joint conditional statistics of species mass fractions, mixture fraction, scalar dissipation, flame orientation, and flame curvature may be quantified. The first results, using this 5-camera, combined imaging system in partially premixed CH4/air jet flames, were presented. Original is an abstract.
