XFlow CFD is used by leading aerospace companies for modeling many aspects of aircraft and aircraft component design.

 

Application Areas Include:

  • Aerial Maneuvers
  • Transonic & Supersonic Flows
  • Moving Parts
  • HVAC and Cabin Comfort
  • Water & Fuel Management
  • Take-off and Landing Configurations (High Lift)

Aerial Maneuvers:  XFlow accurately predicts the effects of flight manoeuvers like pitch capture or dutch roll.  These are normally difficult to capture reliably with traditional CFD, necessitating significant additional development costs for wind tunnel and flight testing.  Shown is an XFlow CFD simulation of the airflow during a Cobra maneuver performed by a Sukhoi SU-37.

Transonic & Supersonic Flows:  Unlike some LBM implementations, the XFlow kinetic solver allows the modelling of unsteady transonic and supersonic flows at arbitrary Mach numbers. The solver is able to capture shock waves and simulate fully compressible flow.

Moving Parts:  XFlow's ability to solve problems involving moving parts with ease allows the analysis of varying conditions like the deployment of the landing gear, stowing flaps, or movement of rotorcraft rotors.

HVAC and Cabin Comfort:  XFlow can simulate the heating, ventilation, and air conditioning system in  aircraft cabins. It is possible to analyze the interior airflow, measure temperature at different locations, and even calculate the passive scalar transport of gas, droplets, or particles.

 

Water and Fuel Management:  XFlow can effectively model free surface flows easily and accurately, allowing engineers to study phenomena such as fuel tank sloshing and aircraft ditching in water.

High Lift Configurations:  It is possible to compute the polar of an aircraft from the linear range to the stall region even for take-off or landing configurations. Detailed full aircraft geometries, including moving landing gear and control surfaces, can be analyzed easily due to the flexible discretization approach.
