- -- Computational Fluid Dynamics (CFD)
- A method that uses numerical analysis and algorithms to solve and analyze problems involving fluid flows.
- -- Drag Force
- The resistance force exerted by a fluid on an object moving through it, directly affected by the object's shape and velocity.
- -- Lift Force
- The component of the aerodynamic force that acts perpendicular to the relative wind direction, crucial for flight dynamics.
