“Pele” is the Exascale Computing Project’s application suite for high-fidelity detailed simulations of turbulent combustion in open and confined domains. The suite of C++-based codes comprises several repositories — PeleC (compressible solvers), PeleLM/LMeX (low-mach flow solvers), PelePhysics (thermodynamics, transport, and chemistry models), and PeleMP (multiphysics models) — that integrate block-structured adaptive mesh refinement (AMR) and cut-cell methods to simulate multifaceted combustion processes. Pele simulations provide the detailed physics and geometrical flexibility to evaluate the design and operational characteristics of clean, efficient, next-generation combustion technologies, including advanced ICEs for automotive, industrial, and aviation applications.

In this episode of Let’s Talk Exascale, Jackie Chen from Sandia National Laboratories describes the Combustion-Pele project, which uses predictive simulation for the development of cleaner-burning engines. “Almost all practical combustors operate under extremely high turbulence levels to increase the rate of combustion providing high efficiency, but there are still outstanding challenges in understanding how turbulence affects auto-ignition.”
