Applied Aerodynamics Group

Welcome to our group page!
We are a part of the research teams of Computational Fluid Mechanics Laboratory (CFM Lab), Hokkaido University. The main research themes of our group can be divided into following categories:

We have a strong industrial network. Most of our research studies are collaborative works with the automobile companies in Japan. This provides our group members a valuable opportunity to work on solving real-life problems. In addition, we are also maintaining good partnership with other educational and research institutions. We love to work with people of the same interest in pursuing our research goals.

In practice, most engineering solutions for real-life problems that involved fluid flows were overly simplified due to the inability of solution methods to properly simulate the complex flow scenarios. This could lead to high discrepancy between expectation and reality. To overcome this limitation, we aim to develop a robust simulation tool that can treat a variety of complex flow problems.

We have been optimizing our Computational Fluid Dynamics (CFD) tool, namely FrontFlow/red-Aero-HPC, to improve the realism in simulations. By far, we have been successfully applying it to study the behaviors and effects of various complex fluid flows that exist in real life. For example, the dynamic motions of a solid object immersed in a flow such as the case of a moving vehicle, gusty crosswind, turbulence, magnus effect of a sphere due to spinning, etc.

Our in-house CFD code is based on the large eddy simulation (LES) method. It is a highly vectorized and parallelized code designed for high-performance computing purposes. We have experience solving a vehicle flow with around 2.5 billion numerical elements by more than 16 thousand cores of cpu on the K computer, Kobe, which was rated the world fastest supercomputer in 2011.

As a part of the K computer program, Dr. Tsubokura has initiated and administrating the Consortium of The Next Generation Vehicle Aerodynamics Simulator. At present, the consortium comprises members from thirteen industrial companies and five universities nationwide.
