<p>Thank you for the information.<\/p><\/p>\n

  1. the velocity looks wrong if it’s zero at the inlet. Anyway, the flame speed of stoichiometric h2-air is about 2.4 m\/s. This means that the flame will move upstream. So, it’s not possible to get a flame shape looking like that in the paper. A quick calc (with some assumptions) shows that Re = rho*U*L\/mu = 1.2*1*0.002\/2e-5 = 120. So the flow is probably laminar.<\/li>\n
  2. the EDC model in general will require some kind of “ignition” (either patching or starting from a solution already having a flame). Did you check the temperature field after the initialization? <\/li>\n
  3. The residuals plot does not have a key.<\/li>\n
  4. The mass balance is good but the heat fluxes look very unbalanced.<\/li>\n
  5. Did you check if the parameter values for the Sutherland viscosity actually make sense?<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-395210","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/395210","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/395210\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=395210"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
