Abstract

The modification of a flat plate turbulent boundary layer resulting from the injection of drag reducing polymer solutions through a narrow inclined slot into the near wall region of the flow has been studied. Two component coincident laser Doppler velocity profiles were measured with polymer injection, water injection, no injection and with dilute polymer ocean flows. The immediate effects of polymer injection are a deceleration of the flow, a dramatic decrease of the vertical rms velocity fluctuation levels and the Reynolds shear stress levels, and a mean velocity profile approaching Virk's asymptotic condition. These effects relax substantially with increasing streamwise distance from the injection slot and become similar to those resulting with the polymer ocean cases.
