Study at TCU


Name NISHIBE Koichi
Official Title Associate Professor
Affiliation Faculty of Science and Engineering Department of Mechanical Engineering
Profile My research interests include topics related to multi-phase and particulate flows, performance improvement and active control of unsteady internal flow of positive displacement machines and turbomachinery such as pump, fan, compressor, based on understanding obtained by comparison between Computational Fluid Dynamics (CFD) and Experimental Fluid Dynamics (EFD).
Research Field(Keyword & Summary)
  1. (1) Jets/Synthetic jets

    Clarifies some fundamental flow characteristics of free synthetic jets and synthetic jets near a rigid boundary by conducting an experiment and numerical simulations.

  2. (2)Fluid machinary

    An attempt is made to clarify the flow instabilities downstream of inlet guide vanes and Return vanes by conducting experiments and performing a numerical simulation.

  3. (3) H2 Engine / Oil consumption

    Optimization of internal flow for the development of hydrogen engines using a numerical simulation.
