Spray modeling includes primary and secondary break-up, droplet/droplet as well as droplet/wall interaction. Both spray and wall film models are capable of handling multi-component fuels, surrogate fuels and fuel blends. Combustion modeling is performed by deploying either multi-zone models accounting for reaction kinetics in the flame, pre- and post-combustion regions or by solving more detailed reaction schemes of arbitrary complexity using the integrated chemistry solver. Dedicated kinetic emission models complement the combustion models available with AVL FIRE®. AVL FIRE®’s state-of-the-art core program supports the accurate simulation of IC Engine in-cylinder phenomena by offering high end modeling capabilities for turbulence (including also LES Models), wall treatment and heat transfer. Combustion and Emissions Analysis of in-cylinder physics and chemistry of a 4-Cylinder gasoline engine Multi zone combustion modeling in AVL BOOST AVL BOOST and AVL FIRE® are the industry’s prime choice when reliable results are needed for engine thermodynamics and combustion/ emission development. The intelligent integration of the two software tools facilitates solutions for complex tasks early in the development phase and unsurpassable accuracy during the detailed design phase. SPEEDING UP YOUR PROCESSES The time required to create moving meshes for complex geometries of modern IC engines is reduced to merely hours with AVL FIRE®’s highly specialized, automated and parallelized pre-processing tool FAME Engine Plus. Key features include hexahedron dominated grids, local grid refinements and user-controlled constant grid boundary layer supporting accurate heat transfer calculation.
