Profile My work focuses on developing the light-weight numerical simulation tools that can be applied to wide industry where the model-based development is needed. Especially, my specialty is fluid flows associated with the liquid/gas interface, for instance, liquid film flows, film coatings, breakup of droplets, material processing with melting and solidification. The fundamental approach in my research is formulating the efficient models of heat and mass transfer with applying an appropriate approximation.
Recently, our research group has working on application of a rapidly growing machine learning framework to the research field of fluid dynamics. By applying a physics-informed neural networks to the partial difference equation for the liquid film flows, the computational time to obtain the solution can be largely reduced.
As well as taking a role in teaching at TCU, I am an editorial member of Int. J. Microgravity Sci. Appl.
Research Field(Keyword & Summary)
  1. (1) Surface-tension-driven flows

    Fluid flows associated with a liquid/gas interface, including droplet breakups, liquid film flows, thermocapillary flows.

  2. (2) Microgravity science and application

    Fluid flow, heat and mass transfer, and material processing in the low-gravity environment. In the microgravity environment, the surface-tension-driven flow becomes dominant due to the absence of the buoyancy.

  3. (3) Data-driven fluid dynamics

    Application of the machine learning framework to the field of fluid dynamics simulation.
