STAR-CD is replete with physics models specifically developed for efficiently simulating combustion, multiphase sprays and liquid films, heat and mass transfer, transient and turbulence effects, and moving boundaries.

  • Fuel injectors, including gasoline or diesel primary spray break-up and liquid films
  • In-cylinder flow
  • Combustion
  • Coupling to chemical kinetic solvers, such as DARS and Chemkin
  • SI and CI engines, even when operating in HCCI or CAI mode
  • 1D-3D coupled & multi-cylinder simulations
  • EGR
  • Exhaust and aftertreatment

es-ice

Due to a variety of constraints on the combustion chamber, modern engine design requires that valves generally occupy geometric positions in the engine at one instant in time, while the piston occupies the same position at a different instant. As a result of this overlap, the mesh definition for such gas-side simulations is not trivial. Simple motion of the mesh is not possible due to the distortion that would be generated through the cycle.

es-ice provides a dedicated environment to set-up and run ICE calculations, encapsulating the process and best-practices that CD-adapco has developed in over 30 years of industry experience, automating the setting up and running of the sophisticated moving-mesh technology required for engine simulation. It automatically produces a parameterized meshed template that can be altered for specific engine configurations. es-ice produces a single mesh that can satisfy the full cycle of motion. This is possible because of the ability to add and remove layers of the mesh and change the connectivity of the mesh to maintain cell aspect ratios and quality throughout the entire cycle.

es-ice empowers engineers to produce the highest quality results in the shortest turnaround time, by automating the simulation process, ensuring consistency and repeatability.
