Velocity field characteristics of turbulent jets from round tubes with coil inserts.
Author(s) : RAHAI H. R., WONG T. W.
Type of article: Article
Summary
Results of experimental investigations of turbulent jets from round tubes with coil inserts are presented. For the coils, the ratios of pitch spacing to the tube inside diameter, p/D, are 0.4, 0.7, 1.2, and 2.7 and the effective ratio of the coil wire diameter to the tube inside diameter, d/D, is 0.0275. Results show that the coils with large pitch spacing create a significant increase in the jet's mixing process and the mixing is more pronounced when p/D = 1.2.
