CFD and prediction of bifurcation phenomena in flow field.
In the computational calculation of Navier Stokes Equations, we need
to carefully select the formulation method of boundary conditions.
In our research, some of predefined formulations are examined and
it is revealed that many of them show unrealistic result inside
of the calculation region.
Therefore, we presented a new method which present more probable
result.
We also have an interest in rotating flows and try to examin the
bifurcation phenomena caused by the nonlinear dynamics.
