Combustion model software

Convergent Science has integrated Advanced Combustion GmbH's Representative Interactive Flamelet (RIF v4.0) model into its CONVERGE CFD software. Used to model the ignition, combustion, and emissions within a diffusion flame such as those found in a diesel engine, RIF maps the multidimensional flame front to one dimensional flamelet equations based upon mixture fraction. According to Convergent Science, this decoupling of chemical and turbulent time scales greatly reduces the computational expense associated with combustion modeling. RIF 4.0 allows for multiple flamelets and multiple spray injections. Optimized to run more efficiently in parallel, RIF 4.0 also now makes use of the analytical evaluation of the Jacobian matrix. CONVERGE CFD software automates the meshing at runtime with a perfectly orthogonal Cartesian mesh, eliminating the need for a user-defined mesh, claims Convergent Science.
