Abstract

The development of the wake flowfield behind a symmetric cascade of finite-thickness flat plates in steady two-dimensional laminar incompressible flow is investigated for a wide range of Reynolds number. A spectral method is used to obtain the solution to a low-Reynolds-number expansion of the Navier-Stokes equations as well as a second approximation to the Oseen equations. Comparisons to the results of the second Oseen approximation are made with previously obtained solutions to the slender-channel equations for large Reynolds number as well as with solutions to the low-Reynolds-number expansion.
