 Abstract:
The gas dynamics of high velocity oxy fule can be described by the conservation continuum equations of mass continuity, Navier-Stokes, a form of turbulence model and the equation of state, to account for the density variation in the flow field.In regards to combustion, a reduced kinetics(eddy-dissipation model) of one-step global reaction was validated against measurement in the literature and good agreement was found.However, in all the previous studies the inlet condition of the gases into the domain were considered to be constant mass flow rate inlet without taking into account the variation of the densities of the gases.In this study the equation of state is implemented via user defined function into ANSYS FLUENT code to correlate the variation of density to the temperature and pressure as this revealed more about the flow behaviour in HVOF process.
