Pseudospectra를 이용한 평행 평판 사이 유동에서 가장 불안정한 경우

The most unstable case in plane Poiseuille flow on transition by using pseudospectra method

The most unstable situation of laminar plane Poiseuille flow for transition to turbulence is investigated by using a pseudo-spectral method. A number of various disturbance modes are tested and it is found that the flow is the most unstable when it is disturbed by an oblique wave with an angle of $29.7^{\circ}$.
