DISTRIBUTION OF WALL SHEAR STRESS AND CROSS FLOW IN THREE DIMENSIONAL TURBULENT BOUNDARY LAYER ON SHIP HULL

A method for measuring the wall shear stress on the hull of a ship model using a three-hole Preston tube is described. By tracing the friction vectors along their directions, the limiting streamlines are obtained. The velocity distributions in the boundary layer are also measured using the three-hole Pitot tube. Some of the cross flow profiles measured at the after stations are of the type of the so-called reversed cross flow. Further, the author proposes a new prediction method for the development of the three-dimensional turbulent boundary layer on a ship hull on the basis of the assumption of the reversed cross flow profile and the employment of the moment integral of crosswise momentum as an additional auxiliary equation. The results of the calculation agree fairly well with those measured.
