Aerodynamics is the study of the moving air around or inside solid bodies, or in an other perspective, the study of a moving body in the air. Most of the aerodynamic quantities can be well analyzed by an aerodynamics simulation using a cutting edge CFD solver.
Most important quantities I can provide my customers with:
- aerodynamic drag simulation and calculation
- lift calculation
- moment and center of pressure
- turbulence, separation and vortices
- pressure loss calculation
- and many more: service request
Internal Flow Aerodynamics Simulation
If your problem is an “internal flow” case, whereas the fluid is confined by walls in every direction, most important aerodynamic quantities involves pressure loss, friction, local velocity and turbulence. These quantities can be very well simulated and predicted for your product, way before it gets manufactured. This means cost and time savings for you.
Examples for internal flow aerodynamics applications:
- pipe flows
- duct flow in HVAC applications and building air-conditioning
- turbomachinery
- diffusors
- nozzles
- sudden contractions and expansions
- valves
- fittings
- elbows in piping systems
- heat exchangers
- general industrial flows
Outcomes from an internal flow simulation:
- reduced pressure loss
- improved mass flow / volume flow rate
- lower turbulence for lower losses
- or improved turbulence and mixing for special purposes
- reduced noise levels
External flow aerodynamics simulation
The fluid dynamics problem is called external, when the air has an impact on the outer surface of a body. This results in aerodynamic forces, which is the main aim of running an aerodynamics simulation. A CFD software can accurately predict these forces (usually called lift and drag), calculate drag coefficient and lift coefficient and many more.
Typical external aerodynamics applications:
- aerospace and drones
- projectiles and bullets
- ground transportation: cars, trains, buses, motor bikes
- ships, motorboats, submarines (also hydrodynamics involved)
- building external aerodynamics
- sports: motorsport, bike, car racing
Outcomes from an external aerodynamics simulation:
- reduced drag coefficient
- higher efficiency, lower consumption/power input
- reduced/improved lift force depending on the application
- improved stability
- higher performance
- lower noise levels
