About This Episode

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.
