So far, engineering design and development have been primarily carried out based on human knowledge, experience, and intuition. Today, however, computers play an important role in assisting the design and manufacture of various engineering machinery, independent of a designer’s skill. Therefore, our laboratory studies fluid analysis techniques integrated with mathematical and data-scientific approaches to create optimal, robust, and intelligent fluid machinery and their systems; from small devices such as household appliances to large systems such as automobiles and aircraft.
