Study of Numerical Simulation & Investigation of Micro-scale Hydrogen & Methene Diffusion Flame

In this project Characteristics of micro-scale hydrogen diffusion flames produced by sub-millimetre diameter (d=0.2 & d=0.48 mm) are analysed & numerically simulated using ANSYS FLUENT v16.Simultaneous, temporally and spatially found out point measurements of temperature, major species concentrations (O2, N2, H2O, and H2), and absolute hydroxyl radical concentration (OH) are made in the micro flames for the first time. The calculated characteristic features and properties indicate that the buoyancy effect is minor while the flames are in the convection–diffusion controlled regime because of low Peclet number. Also, the effect of Peclet number on the flame shape is minor as the flame is in the convection–diffusion controlled regime. Comparisons of measured mean temperature, major species & OH mass fraction for d=0.2 & 0.48 mm with calculated radial profile are made at x=0.1 , 1 , 2 mm along the flame. where, 'x'= Axial height of the flame from the burner surface.
