Manufacturing

XFlow's accuracy and meshless ease of use make it possible to model a wide array of industrial applications easily that would take days, weeks, or months to model using traditional CFD methods.

 

Application Areas Include:

  • Thermal Management for Electronic Enclosures
  • Mixing Processes
  • Other Heat Transfer
  • Flows Involving Moving Parts
  • Automated Production Systems
  • Sports Equipment
  • Non-Newtonian Fluids
  • Droplets, Sprays, and more...

Thermal Management for Electronic Enclosures:  The thermal solver can be used to simulate the cooling of electronic components to keep them within safe operating temperature ranges. The simulation can include convection/diffusion, radiation and conjugate heat transfer, coupled to the flow produced by fans. Fans are modeled either as rotating parts or as surface boundary condition.  Shown is simulation of air flow in an electronic power supply.

Mixing Processes:  XFlow can be used to simulate agitators and mixers for the chemical industry or water treatment plants. It solves single and two-phase flows for immiscible fluids including surface tension.  Moving parts are fully supported and modeled in detail.

 

Heat Transfer:  Shown below, a heat exchanger simulation showing temperature at the midplane.  Below that, an XFlow CFD model of a refrigerator door opening, showing how the cold air spreads out.

Flows Involving Moving Parts:  XFlow's ability to model and define the motion and reaction for moving parts with complex motion and fluid-structure interactin allows it to model a wide range of important industrial processes.  Shown is a model for a ball check valve.

Automated Production Systems:  XFlow can simulate the flow around moving equipment such as industrial machinery and production line robots in fabrication plants. It is possible to prescribe the motion of each object and so reproduce real operational conditions. The trajectories of dust particles can be tracked with the disperse phase model.

Sports Equipment:  In sports such as soccer, tennis or golf, aerodynamics plays an essential role. XFlow simulates the flow around the ball at relevant velocities and measures the drag, lift and side forces acting on it. The ball moves and spins freely depending on the initial linear and angular velocities and orientation set by the user, and on the interaction with the surrounding air.

Non-Newtonian Fluids:  Highly viscous non-Newtonian fluids (e.g. toothpaste, melted plastic, chemical blends) are common in many industrial applications. The complex rheological properties of these fluids can be introduced in XFlow by using the predefined viscosity models available (Newtonian, Sutherland, Cross, Herschel-Bulkley, Power Law, Carreau) or user-defined functions.

Droplets, Sprays, and Atomization:  

 

“The free surface approach in XFlow means nothing less than a revolution in multiphase flow modelling of atomisation and spray processes. I am convinced it will have a big impact on the modelling of propulsion systems, fuel burners and a wide range of different industrial spray processes.”
