In the early stage of a thermo-fluid system design process, the geometry is not yet defined (the full 3D solid model of the flow path geometry is not available). At this design stage, a flexible method of changing the geometry and elements of the thermofluidic system is very useful for estimating leakage, cooling or purge air flow parameters for different fluid path sections while taking into account the heat exchange of the cooling flow with metal surfaces.
Some Application Examples:
- Hydraulic networks
- Separating and mixing
- Heat exchangers
- Secondary air systems
- Anti-icing systems
- Turbine secondary flows
- Turbopump secondary flows
- Ventilation system
- Generator / electro-engine cooling
Solvent
AxSTREAM® NET is a 1-dimensional system modeling analyzer based on the finite volume method, using a thermo-fluid network approach to simulate secondary flows and heat transfer in steady-state and transient conditions. The absence of 3D geometry allows for use before finalizing the blade geometry while providing good accuracy in results in a very short calculation time. This helps to significantly reduce aerodynamic cooling losses and the recurrence time required to optimize machine performances.
Automation
For enhanced flexibility and automation, AxSTREAM® has extensive scripting capabilities (C # language) to calculate user-defined properties. Data exchange between AxSTREAM NET and other software provides tight integration that is useful for performing multi-run calculations as well as multidisciplinary optimization tasks.
