| 研究実績の概要 |
Conducting computational fluid dynamics (CFD) simulations of sports under real-world conditions presents a myriad of challenges that must be tackled to produce accurate results. To address these challenges, researchers have developed a state-of-the-art CFD framework that is capable of reproducing real-world conditions in numerical simulations with unprecedented accuracy. This framework is the culmination of two key innovations that represent significant breakthroughs in the field of sports simulation. The first innovation is a novel immersed boundary method that accurately represents complex geometries and boundary conditions. The second innovation involves the incorporation of a Lagrangian-Eulerian framework into the CFD solver CUBE. This framework enables the solver to handle complex moving and deforming geometries in a computationally efficient manner. By leveraging these advancements, researchers have been able to successfully apply the framework to real-world sports scenarios, such as swimming and ski-jump simulations. These simulations have demonstrated the framework's effectiveness in accurately modeling real-world sports scenarios, and have highlighted its potential for future research and analysis in sports science and engineering.
