RISIn-Cylinder Flow Computational Fluid Dynamics Analysis of a Four-Valve Spark Ignition Engine: Comparison Between Steady and Dynamic Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical and experimental techniques were applied in order to study the in-cylinder flow field in a commercial four-valve per cylinder spark ignition engine. Investigation was aimed at analyzing ...
A Preconditioning Mass Matrix to Avoid the Ill-Posed Two-Fluid Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-fluid models are central to the simulation of transport processes in two-phase homogenized systems. Even though this physical model has been widely accepted, an inherently nonhyperbolic and ...
