Research Contents

  • The interest our group covers a very wide range of fluid mechanics.
  • In particular, our attention is focused on the stability of fluid flow.
  • Instability of fluid flow accompanies a break in flow pattern symmetry.
  • Oscillatory fluid motion may also occur as a result of flow instability.
  • We can control such oscillatory fluid motion and a flow patten if the theory of flow stability is appropriately applied.
  • Oscillation can also be intentionally induced in a flow by applying the knowledge of the flow stability.
