Argonne conducts largest-ever simulation of flow inside an internal combustion engine

Simulation of the compression stroke of an internal combustion engine

Snapshot from a direct numerical simulation of the compression stroke of an internal combustion engine. During a compression stroke, the piston moves from the bottom-most to top-most position. As the piston moves up, the fluid motion inside the combustion chamber of the engine becomes even more turbulent. (Image: Argonne National Laboratory)
