1D-System simulation

1D-flow system simulation assesses the application of the system. It is used in the automotive branch as well as in plant engineering. The objective is to synchronize individual components so as to achieve optimal overall functioning.

With this approach test cycles are investigated in the motor development. The system is evaluated in terms of  fuel consumption, performance, torque and emissions. In plant engineering the regulations (e.g. for valves or  outlets) are investigated and optimized.

It is important to note that a system simulation requires an enormous volume of data input. Rather than relying solely on literature values, correlations and estimations, using 3D-flow simulations  (CFD) is becoming increasingly popular.

This enables the performance of individual components (e.g. turbochargers) to be stored as a characteristic map.

Moreover, with 3D-CFD resistance coefficients and heat/thermal transfer coefficients can be calculated.
