| Abstract: | By using ADV (Acoustic Doppler Velocimeter) measurement techniques, the turbulent characteristics of a round jet in stagnant surroundings are studied in this paper. Through the special analyzing WinADV software, several characteristics are acquired, such as the profiles of turbulence intensity , skewness, kurtosis and Reynolds stress, as well as the variation of the instantaneous velocity and of turbulence intensity on axis. Furthermore, all the results are compared with other relative results at home and abroad. |
