Experimental Studies of the Fluid-Dynamical Parameters in the Triangle or Square Subchannel of a Rod Cluster of S/D = 1

摘要

A method for measurement and evaluation of data in isothermal flow is described. The measurements were performed in an open-loop air circuit on scaled-up models for a range of Reynolds numbers Re = (25:128) x 10 exp 3 . Results of measurement are given for the average coefficient of friction, the distribution of shear stress at the wall along the circumference of the channel and the velocity field over the channel cross-section. The results of measurement are presented in the form of analytical relations. (Atomindex citation 12:610549)
