A Local Disturbance in Poiseuille Flow

The stability of a local disturbance in Poiseuille flow is investigated in the article. The numeric method have based on eigenvalue problem for partial differential equations. Digitization of a problem is carried out by collocation with Chebyshev polynomial of the first kind. Algebraic eigenvalue problem was solved by iterative methods.

Key worlds: hydrodynamic stability, Poiseuille flow, partial differential equations, spectral methods.
