<About awarded research>
Multiphase flows including solid particles are often encountered in many engineering fields. Because the multiphase flows are extremely complex phenomena, the introduction of numerical method is desired for the better understanding. DEM-CFD method is one of the most practical methods for the solid-fluid coupling problems. Although the adequacy of the DEM-CFD method has been proven in previous works, it is still of great difficulty to calculate the multiphase flow with thin walls and/or confined channels. This is because the CFD grid size should be sufficiently larger than the particle diameter due to the Local volume average technique. To solve this problem, we propose a flexible discretization method, so-called the refined grid model. The adequacy of the refined grid model is proven through validation tests.
It’s my great pleasure to win this award. I really thank Prof. Mikio Sakai for his excellent supervision and also all members of my laboratory. I will try to improve my researches.
