IC Engine in-cylinder analysis is particularly challenging in the respect that extremely complex physics occurs on short timescales and within a moving geometry.
To aid the setup of these calculations and visualization and interpretation of results, CD-adapco has developed a pre- and post-processing environment, es-ice, to complement the STAR-CD solver.
The pre-processor provides the user with all the tools necessary to generate computational meshes that accurately capture geometric details and to set up operating conditions and modeling choices including automatic template generation.
As the solution evolves, meshes appropriate to particular phenomena can be introduced by accurately mapping the solution at a prescribed time in the engine cycle.
es-ice can also be used to set up multicylinder calculations with full intake and exhaust manifolds. This can be particularly useful for modeling phenomena for which 1-dimensional codes are inadequate. Results from a V6 engine with complete intake and exhaust systems are shown in picture 7.
