Mechanics of Fluids and Thermo-fluids
- Thermal Engineering and Science Group (Kawahara Lab.)
-
Our group studies thermo-fluid phenomena and their application to thermo-fluid systems. Research topics include fundamental mechanism of cavitation phenomena, heat transfer process in various cooling technique and its application to blade cooling for gas turbines, chaotic behavior in natural convection fields, numerical prediction of thermo-fluid phenomena, and inverse approach to heat transfer problems and its application to optimal design and control.
- Fluid Mechanics Group (Goto Lab.)
-
This group studies various nonlinear phenomena in fluid mechanics for their deep understanding and for their engineering applications by means of effective combination of mathematical analyses, laboratory experiments and numerical simulations. The current group studies the following specific topics: (1) transport and mixing in flows, (2) flows of complex fluids, (3) turbulent flows at high Reynolds numbers, (4) interfacial flows, (5) nonlinear waves and vibrations in fluid-structure systems, and so on.
Mechanics of Solid Materials
- Nanomechanics and Physics Group (Nakamura Lab.)
-
Our group studies the strength and structure-derived functionality of solid materials from the atomic and electronic viewpoints. Our main research topics include deformation behavior of inorganic materials in light, novel functionality of ceramics based on dislocation engineering, mechanical-electrical energy conversion in ferroelectrics, atomic-level structural analysis of lattice defects by transmission electron microscopy, new atomic force microscopy techniques, hydrogen embrittlement of metallic materials, and nano-diamond composite materials.
- Solid Mechanics Group (Tarumi Lab.)
-
Resonance of sound and ultrasound is studied to evaluate functional materials, develop elastic-wave devices, detect the remaining life of aging structural materials, and apply the sonoluminescence-photocatalyst interaction to decompose organic compounds. In particular, the electromagnetic-acoustic resonance (EMAR) has been investigated, which for the first time makes it possible to measure the elastic and inelastic properties of composites, electric materials, thin films, superconductors, metal glasses, etc. These acoustic measurements incorporate with the micromechanics theoretical models to evaluate the physical acoustic phenomena from the mechanical viewpoint.
