Recently, there have arose many engineering problems which cannot be addressed only with traditional approaches. A representative case of such problems can be found in the demand for miniaturizing engineering solutions. Specifically speaking, novel explanations and governing rules are required for the fabrication of a tiny blood sensor with a size of a few millimeters and the thermal analysis of electronics with tens-of-nanometer-scale channels. The former and the latter necessitate the understandings of microfluidic behaviors of blood and boundary scattering of energy carriers in the narrow channels, respectively. Additionally, a multidisciplinary approach is necessary for engineering problems such as the developments of clean combustion technology and a highly efficient motor, which can contribute to reducing fine particles in the air and improving the driving mileage of electric vehicles. The faculty members in this group have been challenging ‘multi-scale and multi–physical’ issues.
