Analysis of the Velocity Mixture through a Partially Premixed Burner: Modeling, Simulation and Validation
Abstract:
The problem of lack of knowledge of the parameters and variables involved in the mixture mechanics of a partially premixed burner results in the production and improvement of these components by means of heuristic methods. Mathematical modeling, CFD (Computational Fluid Dynamics) simulation and validation, of the primary, secondary air velocity, and of the methane-oxygen mixture through the burner was developed. The mathematical model was constructed from the general energy equation. The measurement of the velocity of primary and secondary air and the output of the mixture was carried out using the PIV (Particle Image Velocimetry) technique. The results show that the speed of the mixture through the burner is a function of the cross-sectional area, the pressure, and the density of the mixture in the various sections. The correlation of the values obtained between the mathematical model and the CFD simulation is 0.97; the experimental results and the simulation shown an average difference of 0.65 m/s in relation to the primary and secondary air velocity, and the mixing output. It is concluded that, based on the knowledge of the parameters that govern the mechanics of the mixture, it may be possible to propose a methodology to design this type of components based on scientific and engineering foundations.
