| Abstract(E) | As the circumstances surrounding the development of automotive internal combustion engines have become increasingly complex, there is a growing need to reduce the cost of CFD simulations, one of the key analysis tools, and to improve its prediction accuracy. In response to this demand, the authors have been developing a CFD code that employs cell-based AMR and high-order discretization methods. This paper presents the progress of these efforts, along with demonstrative computational examples. |
