Boundary layers of a flat plate located parallel to the mean flow in the downstreams of a cylinder row in motion were empirically examined, in order to obtaine fundamental knowledges concerning the mutual interference between blade rows working in a viscous incompressible fluid. Influenced by the fluctuation in the main stream velocity, a unique turbulent boundary layer, which may be called "forced turbulent boundary layer", was developed at a distance from the leading edge of the flat plate. This boundary layer has several properties different from those of ordinary turbulent boundary layers. The characteristics, such as mean and fluctuation velocity distributions, of the forced turbulent boundary layer as well as of the boundary layer under transition to this type were investigated. With increased fluctuation velocity in the main flow around the leading edge, the thickness of the boundary layer in the reg on near the leading edge increases. Factors influencing this phenomenon were studied.
