flownex® & ansys
co-simulation
Flownex® SE is able to couple to a range of Ansys products which opens a new frontier in co-simulation. This gives users the ability to simulate complete and integrated engineering systems quickly and accurately.
WHY USE FLOWNEX® SE WITH ANSYS?
WHY USE FLOWNEX® SE WITH ANSYS?
State of the art fluid models in Flownex® SE can accurately model 1D flow and 2D heat transfer. This can be used to replace 1D flow in 3D flow simulations: in doing so mesh sizes can be reduced and solving times can be drastically decreased. Flownex® SE contains component models ideal for modeling large, interconnected systems and can be coupled to 3D simulations to transfer the change in component performance to a change in overall system performance.
Design
- Include large systems into the design process which would be impractical when only using 3D CFD.
- Reduce simulation complexity by reducing large systems into sections that can be simulated by 1D CFD and parts where 3D CFD is needed.
- Include complex geometry conduction for heat exchangers, boilers, etc.
Analysis
- Analyse real system behaviour by including the entire system into the design process.
- Determine and investigate thermal stress distribution in complex geometry.
- Analyse and determine flow characteristics in custom complex regions.
Optimisation
- Use different tools such as the Designer, Optimiser and Sensitivity Analysis to determine optimal design parameters.
- Run multiple runs with different operating conditions or inputs using Parametric studies.
- Compare and optimise different system layouts quickly and easily.
EXAMPLES
TRANSIENT THERMAL STRESSES
EFFECT OF START-UP & DYNAMIC LOAD CHANGES
Couple Flownex to Ansys Mechanical to determine the thermal stress distribution in materials surrounding flows.
Boiler tubes in thermal power plants experiences a wide range of thermal stresses due to varying loads. The boiler walls need to be designed such that it can handle these thermal stresses, especially during start start-up conditions.
SIMPLIFIED HEAT EXCHANGER
MODEL COMPLEX EXTERNAL GEOMETRY WITH 3D WHILST MODELLING THE INTERNAL FLOW WITH 1D SIMULATION
Couple Flownex to 3D CFD software packages such as Ansys CFX and Fluent to include complex 3D flows into your 1D thermal system.
Data centre HVAC systems are highly integrated and complex. Flownex can be used to model the thermal management system and cooling, while Fluent or CFX can be used to include complex 3D flows in data centre rooms.
LONG TRANSIENTS
COUPLED FLOW SIMULATIONS
Couple Flownex to Fluent or CFX to reduce mesh sizes for 3D CFD computations.
Flownex can be used to model the heat exchanger internals and tube walls, while Fluent or CFX can be used to simulate the shell flow.
