Engineers use Computational Fluid Dynamics (CFD) simulations to speed development and optimize Diesel, spark-ignited, 2-stroke, HCCI, and dual-fuel reciprocating engines. Join this workshop to gain hands-on experience with commercial CFD software, as well as technologies in the simulation eco-system that support, augment, and streamline CFD applications for engines. ANSYS experts will lead the workshop, sharing best practices and simulation strategies, including the following topics:

  • Set up solution-adaptive mesh refinement to resolve dominant physics and combustion characteristics, with automatic mesh generation in ANSYS Forte CFD
  • Define your fuel model to provide accurate fuel combustion and emissions predictions, considering soot particle size-distribution tracking, spark-ignited flame propagation, engine knock and fuel effects, using the ANSYS Model Fuel Library
  • Calculate compositions for port-fuel, direct-fuel, gas-injection, and dual-fuel simulations
  • Use reference frames to set up a multi-cylinder 4-stroke engine simulation
  • Set up a 2-stroke engine with sliding interfaces between the piston and port openings
  • Parameterize geometry and set up a Diesel piston-bowl shape optimization, with review of available tools to prepare or import geometry
  • Analyze and visualize results using post processing tools ANSYS EnSight and CFD-Post
  • Concept to Design: use 0-D and 1-D models in ANSYS Chemkin-Pro that complement CFD
  • Set up a co-simulation with GT-Suite®
  • Apply thermal and structural analyses of the engine block
  • Use the Command-Line Interface for full scripting control and simulation-component reuse
