Welcome to Kawai-Asada-Kawai Laboratory
Welcome to Kawai Laboratory (Aerodynamic Design Research Group) at the Department of Aerospace Engineering, Tohoku University.
Our research combines theoretical analysis, computational physics, data science, and high-performance computing to develop novel high-fidelity numerical simulation methodologies. These methods enable us to uncover the fundamental flow physics of complex, compressible, multi-scale, and multi-physics flows in aerospace engineering, as well as to create next-generation aircraft aerodynamic design methods. Our interests span a broad range of topics in fluid mechanics, with a focus on compressible flow, turbulence, shock waves, mixing and combustion, high-fidelity numerical methods, data science, physical modeling, machine learning, uncertainty quantification, and related areas in aerospace engineering. For details on current and past projects, please see Research.
Our group is also engaged in the MEXT Program for Promoting Researches on the Supercomputer Fugaku, focusing on digital transformation (DX) in aircraft development through digital flight. Using the world-class computing power of Fugaku, we demonstrate aircraft digital flight by integrating high-fidelity simulations with data-driven science. In collaboration with the Mitsubishi Heavy Industries Group, we are advancing innovative DX technologies for next-generation aircraft design and extending the outcomes of this research to a wide range of industrial products.
We are currently not accepting IMAC-G students or internship applicants unless Soshi Kawai receives a direct email recommendation from a professor who knows the applicant well.
