High-Reynolds-number asymptotics of the steady flow through a row of bluff bodies

An extension of an earlier theory of the two-dimensional incompressible flow past an isolated body is described. For a crossflow cascade of bodies, each of unit size in the crossflow direction and distance 2H apart, the region of validity of the extended theory covers H [Gt ] 1. A comparison with recent numerical calculations is favourable and a tentative asymptotic structure for the case of H = O(1) is described.
