A Study of Boundary Layers in the Downstreams of a Cylinder Row in Motion : 2nd Report, Theoretical Investigation on the Boundary Layers of a Flat Plate

Abstract

A unique turbulent boundary layer-forced turbulent boundary layer-which is found on a flat plate located, with zero incidence angle, in the downstream of a cylinder row in motion in the 1st Report is investigated theoretically in this report. As a result, (1) An unknown function in the experimental formula of velocity distribution in the boundary layer under transition to forced turbulent flow is calculated by means of the equation of mean motion. (2) The mean friction coefficient in the transition region is calculated by means of the equation of momentum. (3) The position where the transition is concluded is estimated theoretically. (4) In the region where the forced turbulent boundary layer is fully developed, the mean friction coefficient is estimated theoretically.
