Paper Abstract

Difficulties of LDA for the near-wall turbulence measurement are well known. The measuring error increase at drawing near to a wall. Joint use of laser anemometry in a flow and measurings on a wall remove it. Existent methods permit the measurement of average values and pulsations of friction and pressure on a wall with good accuracy. The offered method of their processing is based on the harmonical analysis of experimental values of amplitudes and phases. The near-wall flow is calculated on the basis of simplified equations of Navier-Stokes. The obtained solution may be grown together with the values determined on the basis of the LDA measurings, which are carried out with a high accuracy in to distance from a wall.
