CFD Knocks the Knock

Computational fluid dynamics package has particular application to internal combustion engines.

“When fuel improperly ignites, it interferes with the engine’s cycles, causes damage to components and impacts the vehicle’s performance,” said Bernie Rosenthal CEO of Reaction Design (reactiondesign.com), a developer of FORTÉ, a computational fluid dynamics (CFD) package that has particular application to internal combustion engines. This improper ignition—a.k.a. “knock”—is now being addressed in FORTÉ though the use of a solver that the company has added to the CFD package. They’re using a multi-component gasoline fuel model—including hundreds of chemical species and their corresponding kinetic reactions—rather than a reduced fuel chemistry model, thereby providing a level of reliable modeling otherwise not readily attainable.
