A Chebyshev-collocation method is applied for the calculation of the Navier-Stokes equation. For the supercritical transition, the simulation starts with an initial velocity given as the basic flow plus small disturbances, and the evolution of the these disturbances is pursued until the flow breaks down to turbulence. On the other hand, the secondary instability induced by a flow given as the basic flow plus a Tollmien-Schlichting wave with a large assigned amplitude is simulated for the subcritical transition. Numerical results obtained by the simulation agree well with ones obtained by the linear stability theory and experiments.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
