2, the curve indicated by the broken line is a methane number calculation curve in which A 2.0 in Equation (1), and the curve indicated by the alternate long and short dash line is the methane number in which A 2.0 in Equation (1). The flexible AVL BOOST ™ 3D-approach to simulate linear acoustics delivers highly accurate solutions even in high frequency ranges. The reference methane number calculation curve is set in consideration of, for example, the gas composition of LNG vaporized gas that may actually exist. If the entered numbers exceed 100 mol, the amount of CH4 is automatically. The calculation result indicates whether or not the given gas quality is suitable for use in Wrtsil dual-fuel engines. ![]() Identical modelling of physics and chemistry in aftertreatment systems empowers engineers, designers and developers to seamlessly switch between 1D and 3D models at any stage of the development phase. We have developed this tool for ship owners and operators to calculate the Methane Number of the fuel gas. Coupled with AVL FIRE ™ users are able to accurately account for 3D flow and heat transfer effects in pipes, manifolds and combustion chamber. This is accomplished with an internal solver for chemical reactions. Can I calculate linear acoustic simulation without requiring additional engine data?ĪVL BOOST™ provides a comprehensive species transport for a high level of flexibility regarding fuel composition and working gas.Can I predict orifice noise and design brandsound?.Can I calculate individual components as well as the whole exhaust aftertreatment system?.How closely do the simulation results correlate with real world driving emissions (RDE)?.Can I optimize the transient response considering mechanical inertia and gas dynamic effects (eg. ![]()
