Parallel Session Descriptions

Engine Facilities and Rapid Compression Machine

Argonne’s engine testing capability spans from light-duty to heavy-duty, with engines ranging in size from 0.5L up to 19L. Argonne’s facilities include state-of-the-art instrumentation for in-cylinder visualization and regulated and un-regulated emissions characterization (gaseous and particulate). These experiments generate high-quality data for validation of VERIFI simulations. Argonne is also the only national laboratory with a rapid compression machine for generating very controlled, engine-like conditions for studying fuel ignition and combustion properties.

Argonne Leadership Computing Facility

The Argonne Leadership Computing Facility (ALCF) is a user facility at Argonne that provides the computational science community with a world-class computing capability dedicated to breakthrough science and engineering. The tour will include a visit to Argonne’s 10-petaflop MIRA supercomputer. The VERIFI team uses these facilities and collaborates extensively with ALCF scientists to scale up engine calculations.

One-on-One Session

VERIFI experts will be available for discussions with industry representatives to understand their computing needs and provide guidance on how VERIFI projects could help them design and optimize next-generation engines and fuels. Argonne will provide a list of VERIFI experts available for discussion.
