TCAE

This time, we compared the aerodynamics of two official FIFA World Cup match balls:

• Al Rihla – used at the FIFA World Cup 2022

• Trionda – announced for the upcoming FIFA World Cup 2026

What did we simulate?

Using high-fidelity CFD simulations in TCAE, we analyzed the airflow around both balls across a range of realistic kick velocities and spin conditions. The focus was on:

• Surface panel geometry and seams

• Flow separation and wake structure

• Aerodynamic stability and force fluctuations

Why does it matter?

Even small geometric changes in panel layout can significantly influence:

• Ball stability in flight

• Drag and lift behavior

• Predictability for players and goalkeepers

These effects are subtle—but at elite levels of football, they matter.

Engineering insight beyond football

While this study is a fun and visually attractive example, the underlying physics is identical to what we solve daily in engineering applications:

• External aerodynamics

• Unsteady flow separation

• Complex surface-flow interaction

It is a reminder that CFD is a universal tool—whether you are designing a pump, a turbine, or a World Cup ball.

Visuals & results

The simulations reveal distinct differences in wake topology and pressure distribution between Al Rihla and Trionda, directly linked to their surface design philosophy. Detailed flow visualizations highlight how modern ball development increasingly relies on numerical simulation rather than trial-and-error testing.
