A Numerical Simulation Methodology and its Application in Natural Gas Burner Design

A numerica 1 methodology has been developed for the design and analysis of gas-fired combustion systems. The fundamental element of this approach is TEACH-3E/II, a three dimensional numerical simulation code for turbulent f lows developed at Imperial College. The simulation technique can treat a wide variety of boundary condi tions, is numerically stable at all Reynolds numbers, and can be applied to a broad class of burner geometries and flows. Examples are presented which demonstrate its use as an effective engineering tool for the analysis of fluid dynamics, heat transfer, and the suppression of pollutants in thermal processing systems.
