Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Power Engineering Summary: The current work involves a numerical studyto validate the numerical models to investigate the effects of the normalized premixing length (L/D) at a certain overall jet equivalence ratio (Ф) and a certain Reynolds number (Re) on the mixing field structure in a concentric flow burner.Also,involves finding the bestnormalized premixing length, L/D, in a concentric flow burner using validated numerical models.Finally, a numerical study of the partially premixed flame structure in a Concentric Flow Conical Nozzle (CFCN) burner by using numerical models,which included calculating the flame curvature and discussing the influence of equivalence ratio on the structure of the flameand finding the lowest value of the equivalence ratio at which the flame be sustainable. All numerical studies were carried out for air-natural gas mixture using ANSYS 2020 R2 Package
