Synopsis


Blockage corrections have been tested against experimental data for various bluff profiles. It is shown that the momentum method corrects base pressures, over the blockage range 0 to 16%, and a procedure for correcting drag coefficients is proposed. It is also shown that the pressure distribution over a rounded profile, such as the circular cylinder, is very distorted by high blockage so that it is unlikely that a really effective correction procedure for drag coefficient can he devised for these conditions.
