摘要
以空气为介质,用激光多普勒测速仪,在渣油气化炉模型中进行了速度分布测定,研究了射流径向增长、轴向衰减、最大回流量、径向速度分布规律。ln[-ln(W/W_m)]=-0.3944+1.4694ln(R/R_(0.5))1/W_m=0.0764[1+(X/X_u)^(5.4717)]R_(0.5)=0.0763[1+(X/X_r)^(4.8017)]Q_m=-0.1124+4.
The axial profile and the radial profile of jetting velocity have been measured using
a Laser Doppler Anemometer with air as flow medium.The axial decay of maximum ra-
dial jetting velocity,axial growth of the velocity half-radius ,circulation flow rate and ra-
dial profile of jetting velocity are
