Aeodynamics

The Single phase solver of XFlow is used by major companies in the aerospace industry. The accuracy of this solver for predicting aircraft aerodynamic behavior has been very well validated on several reference benchmarks such as the 1st and 2nd AIAA High Lift Prediction Workshops, as well as on several applications such as buffet-onset detection and post-stall conditions.

The Virtual wind Tunnel of XFlow reduces the setup time of any external aerodynamic analysis.

Flight Dynamics

The interaction between aircrafts and aerodynamics is one of the new areas explored by CFD. XFlow provides the means to investigate aircraft response subject to aerodynamic loads thanks to its Rigid Body Dynamics capabilities and ability to handle arbitrary moving parts.

XFlow is capable of simulating aerospace applications involving moving parts. This unique capability allows the running of full polar sweep analysis, flaps deployment dynamics, landing gear deployment, turbofan or helicopter blade rotations and any other flight maneuvers.

XFlow enables exploration of new applications of CFD, breaking the limitations of traditional CFD solutions.


Fluid Structure Interaction

XFlow has demonstrated its ability to reproduce results of aircraft behaviors only observable in real flight conditions such as spin control, pitch damping, dutch roll, and ice shedding separation and even FSI with deformable geometries using co-simulations with Nastran, and co-simulations with external MBD software (through FMI standard) to perform complete analysis of ailerons and elevators deployment.

XFlow makes it possible to study behaviors that cannot be reproduced in wind tunnels nor in real flights test, such as aircraft ditching.

Thermal Analysis

The coupling between energy and momentum equations is ensured in XFlow by several thermal models that can be used to simulate the heating, ventilation, and air conditioning system in an aircraft cabin.

Thermal post-processing is straightforward and allows visualization of the evolution of the temperature field inside the aircraft cabins, and measurement of the temperature on the passengers, on a given location using a probe, line, surface or inside a volume.
