Rewriting the Formula for Fireworks

A chemical kineticist optimizes fireworks by increasing displays and decreasing smoke.

Rewriting the Formula for Fireworks

“To solve the problem, Ansys Chemkin-Pro…was used to model the smoke formation within the fireworks and investigate the chemical reactions. This data provided invaluable insights that led to recommendations for smoke reduction.”

Mitsuo Koshi is a world-renowned chemical kineticist who also happens to be an avid fireworks fan. He is responsible for judging prestigious fireworks competitions across Japan. Every year, firework displays become grander and more fantastic, but this is paired with increased emissions.

To reduce the emissions, Professor Koshi started with classical nucleation theory (CNT), but quickly learned it could not be applied to predict the black powder smoke generation. Koshi then looked to Ansys Chemkin-Pro, an unconventional choice at the time. The chemical kinetics simulation software allowed Koshi to quickly model and assess the smoke particles.

Next, the software was utilized as a chemical reaction simulator. During simulation, Koshi could quickly substitute various chemicals until the right combination was found.

Using Ansys Chemkin-Pro, Koshi was able to reduce emitted smoke by nearly 90 percent, making the firework shows less environmentally harmful while providing greater visibility to their fantastic displays.
