The modern automotive exhaust system is critical in enabling powertrain systems to meet their performance, efficiency, weight and packaging targets. However, during the vehicle development process, it is the exhaust system that is often left until the very end to design.
Using the Exhaust Systems Modelling packages, you can model entire systems from the engine to the rear silencer/muffler and subsequently run simulations under real operating conditions to accurately predict pressures, losses, flow rates and other performance parameters for a given design. Rapid simulations and highly accurate results produced by Flowmaster enable you to optimise and evolve a design before committing to build expensive physical prototypes. Once you have a physical prototype you can correlate your Flowmaster model with your test data and then with even greater accuracy understand small changes to the physical design by first modelling them in Flowmaster.
The Exhaust Systems Modelling Packages from Flowmaster provide many tools for the design and simulation of exhaust systems:
- Steady State and Transient simulation options
- Compressible and Incompressible Flowbalancing and Heat Transfer
- Full Heat Transfer in bends
- Weighting Factor for irregular bends
- A wide range of standard and exhaust specific components
In conjunction with the exhaust specific components, standard component catalogues enable you to construct your own custom components including:
- Accumulators
- Electro Mechanical
- Sources and losses
- Pipes, bends, junctions, transitions, orifices
- Solids
- Controllers and Gauges
