摘要
A theoretical investigation was done for the generalized Berman problem, which arises in steady laminar flow of an in- compressible viscous fluid along a channel with accelerating rigid porous walls. The existence of multiple solutions and its condi- tions were established by taking into account exponentially small terms in matched asymptotic expansion. The correctness of the analytical predictions was verified by numerical results.
