A study was made of the effect of a body for example a slender bar, placed in the center of a two-dimensional turbulent jet flow fields, which directly influences the mechanism of fluctuant velocity fields. It was evident in the previous report that the effect of a body on turbulent jet flow fields is different depending on it's locations. Turbulent energy transportation due to a cylinder placed in tuhbulent jet flow fields was investigated by Keffer, Kanamoto & Roshko, but the peculiarity in placing a cylinder in the center of turbulent jet flow fields was not deals with. The present investigation is undertaken to measure the turbulent energy spectrum of turbulent jet flow fields with or without a body, and to study the effect of a body on turbulent energy transportation.
