摘要:
利用粒子图像测速(PIV)技术对双层双折三斜叶涡轮桨式搅拌釜内流场特性进行实验研究，分析釜内液面高度h、搅拌桨安装尺寸C1（离底距）、搅拌桨结构尺寸C2（桨间距）对搅拌釜内流体流动速度、流型及轴向无因次速度分布的影响。研究结果表明，C1的增大能使釜内流场高速区上移，C1=0.28h时近液面区域流体速度得到明显改善，釜内流场速度分布较为合理；C2的增大能改变上下桨叶的配合效果，C2=0.25h时近液面区域流体流速明显提高，釜内流体整体流速较高，两桨叶配合最佳，有利于釜内物料的混合。
Abstract:
The Particle Image Velocity (PIV) technique has been used to study the flow field characteristics in a stirred tank with double two-hinge three-pitched disc turbine impellers. The effects of liquid level height h, installation size C1 (distance from the bottom), and structure size C2 (distance between the blades) on the fluid flow velocity, flow pattern, and axial dimensionless velocity distribution inside the stirred tank were analyzed. The research results indicate that the increase of C1 can cause the high-speed zone of the flow field inside the tank to move upwards. When C1=0.28h, the fluid velocity in the vicinity of the liquid surface is significantly improved, and the velocity distribution of the flow field inside the tank is relatively reasonable; the increase of C2 can change the coordination effect of the upper and lower blades. When C2 =0.25h, the fluid flow velocity in the near liquid surface area is significantly increased, and the overall fluid flow velocity in the tank is higher. The best coordination between the two blades is beneficial for the mixing of materials in the tank.
