A pneumatic conveying system can be considered as a “Complex System”.

A complex system is defined by the following characteristics and criteria:

- Many variables, interacting within the system and with the surrounding (open complex system)

- The outcome cannot be derived from the system variables/properties separately.

- The system contains many feedback loops.

- Nonlinear.

- Must be solved in domain -specific context (time domain or spatial domain)

- Starting values of the solving algorithm must be close to the thermodynamic equilibrium

- Simplifying solving algorithms lead to inaccurate and not useful results.

A pneumatic vacuum unloader/pressure discharger are in fact 2 complex systems, interacting with the ship to be unloaded and with the silo to be loaded.

A complex system can be extended by external system design influences s.a. material properties, ambient conditions, equipment selection, etc.

The pneumatic conveying calculation, developed by www.Yarca.nl , meets all the above criteria.

To present the complexity of a pneumatic conveying calculation algorithm, attached a diagram, showing the involved parameters and their interrelated dependencies.
