  Hello everyone,
  
  I would like to ask if it is possible to generate flamelets for non-unity Lewis number in Ansys Fluent? I've read that the Lewis number is set to 1 by default and there is no direct way to change this, is this true?
  Thanks in advance

  Hi,
  At present, the option to generate flamelets for non unity lewis number is not available in Fluent. One could explore the species transport model with Kinetic theory or Full multicomponent diffusion model to capture non unity lewis number behaviour. May I know the details/application for which you want to explore non unity lewis number formulation.
