A Suggested method for measuring turbulence /

The desirability of a quantitative measure of turbulence is emphasized, and a possible method of attack on the problem is discussed. Data are presented to show that the hot-wire aneomometer has possibilities as an instrument for measuring turbulence. An apparatus consisting essentially of two hot wires, one parallel to the air flow and one at right angles to it, is suggested. Further study of the possibilities of such an apparatus is recommended.NACA TN no. 380."June, 1931."Includes bibliographical references.The desirability of a quantitative measure of turbulence is emphasized, and a possible method of attack on the problem is discussed.
