What Flownex gives you

Flownex software is commonly used to simulate power conversion cycles, cooling equipment and flow distribution networks. The Flownex® Simulation Environment gives engineers the power to perform detailed integrated systems modeling at a swift pace without jeopardising their accuracy.

Users gain access to a conclusive library of:

  • Flow components
  • Full conjugate heat transfer
  • Mechanical components
  • Advanced fluid models and mixtures

All components are validated and verified, built on the foundations of fundamental thermal fluid physics and proven correlations. Flownex is developed in an ISO9001:2008 and NQA1 quality assurance system environment and is the only software of its kind to hold a nuclear accreditation.


How engineers can use Flownex

With access to the Flownex® Simulation Environment, engineers can evaluate a high number of system configurations and simulate multiple fluids in a single network. It also accounts for significant physical phenomena when modelling fluid systems.

Flownex offers the simulation of both analogue and digital control systems through an intuitive interface that has been under constant development for nearly 30 years. Over that time, engineers have been using Flownex to solve specific problems by using custom flow and heat transfer components, fluid models and tools.

With a seamless link between flow/heat transfer networks and integrated control systems we are able to improve design and operational parameters.

All of the above combines to vastly improve engineers’ workflow and productivity within a fluid power simulation environment.

Flownex industry applications

Flownex software has a long and respected track record, and is regarded as industry-leading across a wide range of sector applications, including:

  • Nuclear
  • Aerospace
  • Automotive
  • Oil & Gas
  • Turbomachinery
  • H-VAC
  • Industrial Processes
  • Academic use

In a nutshell, all industrial sectors which deal with gas or liquid transportation in a plant.

FLOWNEX has many technical applications, including:

  • Fluid Flow
    Flownex® SE contains a large library of thermo-fluid components designed specifically for both steady state and dynamic system performance analysis and optimization.
  • Oil & Petrochemical
    Flownex® SE determines pressure drop [flow] and heat transfer [temperature] for the connected components of a complete system in steady state and transient, e.g. pumps or compressors
  • HVAC
    Flownex SE provides HVAC engineers with the ideal systems simulation tool to design and optimize integrated ducting systems, refrigeration cycles and control systems with both accuracy and speed.
  • Supercritical CO2
    Flownex® SE simultaneously solves mass, momentum and energy in conjunction with two-phase fluid properties for system models. This makes it ideal for modelling super critical CO2 cycles where key design parameters can be analyzed and optimized.
  • Turbomachinery
    Flownex SE is an industry leader system modelling tool for the design and analysis of turbomachinery systems, subsystems and auxiliaries.
  • Nuclear Small Modular Reactors
    Flownex SE enables system level modelling of Small Modular Reactor (SMR) nuclear plant fluid mechanics, heat transfer and neutronic response in both transient and steady state.
