燃焼振動の数値シミュレーション―「富岳」の活用―

抄録

Numerical simulations of combustion fields are indispensable recently not only for the understanding of combustion physics but also for the efficient development and optimal design of combustion devices. Because of the lack of computing power and the immature state of turbulent combustion models, however, the accuracy of the present numerical simulations of combustion fields is insufficient. It is strongly expected that the Supercomputer Fugaku, which has maintained its place at the top of the high-performance computing world for the fourth consecutive term, will be great use to researches in the combustion community. One of the most important issues in such combustion researches is the prediction and suppression of combustion instability, which often induces flashback, generates combustion noise and damages combustors. In this article, our recent work on the combustion instabilities by large-eddy simulation (LES) using the Fugaku is introduced, together with some other combustion researches related to the use of High Performance Computing (HPC) systems.
