Краткое описание

Fluid flow characteristics in internal combustion engines have been studied for a long time by experimental approaches. But today, computational fluid dynamics (CFD) simulations have become a useful tool, especially with new, more powerful computers. On another side, experimental tests have become highly onerous and overpriced. In addition, investigations using this kind of methodology are limited to small parts of the system. Thus, an alternative solution to carry out this study is CFD simulation and modeling. The latter is more economical in time and cost. The aim of this article is to explore the flow characteristics during the exchange process, which has a crucial influence on the performance of the internal combustion engine and on pollutant emissions and noise. In this study, two different approaches related to the modeling of engines are tested: CFD simulations using a moving mesh strategy and a zero-dimensional model, the so-called inertial capacitive model. For the first approach, a dynamic mesh model was used to simulate piston, intake, and exhaust valve motion during the open phase of a nonignited single-cylinder four-stroke-cycle engine. The second approach used in this study was retained to the formulation and application of the new (0D) inertial capacitive model based on the first thermodynamic principle, Newton's second law, and the associated laws of fluid mechanics relative to gas dynamics in the intake and exhaust manifolds of internal combustion engines. The subject of the second approach is to check the validity of the CFD analysis and to calibrate some parameters deduced from the tuning process of the problem considered.
