Abstract

In this paper, the author discussed a turbulent flow of a non-Newtonian liquid. Fro, ii th~experimental results of the resistance law to a smooth pipes, the author thought that the w ixinglength theory make clear the Reynolds stress and drived a velocity distribution and a resistancelaw to a turbulent flow of a non-Newtonian liquid from the mixingth length theory. Theauthor showed that the universal constant K is function of x~/x~ that the coeffient of eq. (1.10)of the redistance law is constant. The value of K was showed in Fig. 3. In the next, , , heauthor discussed the kinetic similitude in a Bingham flow. The kinetic similitude of a Binghamflow established when the Reynolds number of eq. (3.11) is equal for the plototype and themodel.
