INTEGRATED SYSTEM ANALYSIS
Analyze the highly complex and interconnected components of space propulsion systems
From rapid rocket engine cycle designs to detailed component development: Flownex® SE has the capability to model and simulate large interconnected rocket engine systems. Using Flownex® SE, pre-burners with complex combustion reactions can be simulated, flow control strategies can be investigated, turbopumps with real-time power matching can be implemented and much more.
Today more sophisticated rockets have been developed, such as the SpaceX Raptor engine. Different liquid rocket cycles have been designed in the past few decades: improving efficiency, power, and safety. This has led to time consuming and costly physical testing and design calculations. To reduce R&D cost and development time, 1D system simulation can be incorporated into the design process.
Minimise time-to-production and speed up commissioning by determining beforehand the energy consumption of a process.
Solve fundamental physics of flow and heat transfer.
Flownex® SE Simulation Environment is a powerful research tool and classroom teaching aid used to demonstrate the physical principles in the fields of fluid mechanics, heat transfer, and thermodynamics. Flownex® SE determines pressure drop and heat transfer for the connected components of a complete system in steady state and transient, e.g. pumps or compressors, pipes, valves, tanks and heat exchangers.
Material on Bernoulli’s principle provides a fundamental explanation of energy conservation in fluid flow and the causes and effects of pressure loss. While the transfer though flat and cylindrical geometries is illustrated by Conduction and the change in temperature with pressure is fundamentally explained by the Joule – Thomson effect.
Solve mass, momentum and energy in conjunction with two-phase fluid properties for system models.
As increased energy efficiency becomes more critical in all forms of power generation, new cycles are being considered by many industries to replace the traditional Rankine cycle. Supercritical carbon dioxide is currently being considered as a potential successor due to a wide range of advantages, such as a reduced physical footprint, the ability to respond faster to load changes and increased thermal efficiency. Flownex® SE is an ideal tool for engineers to use throughout the development of these new power cycles.
sCO2 CYCLE
Design and analysis of hydrogen applications: from fuel cells to the electrolysis of water.
With pressure on industries to move to zero emissions, a strong focus has been put on the research and development of hydrogen applications for decarbonization. The European Union, and others for example, want to get to net-zero greenhouse gas emissions by 2050. One way of doing this is to implement technologies such as hydrogen fuel cells to generate electricity. Green Hydrogen, where renewable energy is used to generate hydrogen from water using a process called electrolysis, is one of the main sources of carbon free energy currently being researched.
Design and evaluate flow and heat transfer systems by using advanced thermo-fluid modelling and co-simulation capabilities.
As the demand for mission critical data centres increases the need for the validation of thermal management systems is continuously increasing. Advancements in simulation now make it possible to evaluate and optimise thermal management systems providing data centre operators with more efficient and robust cooling solutions. Flownex® SE provides engineers with an ideal system simulation tool for the analysis and optimisation of data centre thermal management systems.
Flownex® SE has proved itself as an excellent tool in energy optimisation, slurry modelling, ventilation systems or any other mining-related system simulations.
