摘要：

We present in this study an analytic solution, valid for intermediate Reynolds numbers, of the Poiseuille flow perturbation in a channel. We use a method based on the solution of a linearized form of perturbation equations. The analytic solutions allow us to determine the symmetric and antisymmetric eigenmodes. For any given entry velocity profile in the channel slightly perturbed from Poiseuille flow, the complete flow solution is obtained by using an appropriate orthonormalisation procedure for the bases of the two types of eigenfunctions.
