Airflow around an Aircraft, CFD Simulation with Ansys Fluent

Using ANSYS Fluent, overview of airflow simulation around an aircraft.

Project Description

This simulation uses ANSYS Fluent to explore airflow dynamics around a computational domain-designed airplane.  The objective is to examine the pressure applied on the fuselage of the aircraft together with the profiles of velocity and pressure close by.  Approaching the airplane at a 100 m/s speed, the airflow strikes the fuselage.

Geometry and Meshing

• 3D Geometry Design:Designed with Design Modeler, it simulates airflow by including an aircraft inside a big cubic computational zone.
• Meshing Details: ANSYS Meshing program produced unstructured mesh with 3,190,893 cells for thorough investigation.
   Methodological Approach

• Simulation Setup: steady-state simulation with a pressure-based solver including incompressible airflow circumstances.
• Turbulence Modeling: Simulating turbulence with gravity effects omitted using SST k-omega model.

Conclusion

The simulation outputs offer interesting 2D and 3D contours regarding pressure and speed around the aircraft:

• Pressure Analysis: At the front of the airplane fuselage, one finds maximum pressure.
• Velocity Analysis: At the back of the aircraft is found a separation zone.
• Forces Calculated: On the airplane, the simulation determines a drag force of 16,516.279 N and a lift force of 104,220.68 N.
