最大叶片式桨用于大高径比搅拌釜内假塑性流体混合过程的数值模拟OACSTPCD
Numerical Simulation of Mixing Process in Pseudoplastic Fluids Agitated by Maxblend Impeller in Stirred with High Ratio of Height to Diameter
采用计算流体力学( CFD)技术研究了最大叶片式桨在大高径比搅拌釜非牛顿假塑性流体的流体动力学性能，包括功率特性、剪切性能、排液性能和混合时间。结果表明，在一定范围内桨下端剪切效率高、排液量大，是釜内良好的混合区域。随着雷诺数增加，搅拌流场由双循环流型转变为一个大循环，桨下端两翼剪切能力显著加强，说明剪切量与流体的混合密切相关，混合体积曲线能够从宏观的角度来分析搅拌混合过程。
The hydrodynamics characterization of the maxblend impeller in stirred tank with high ratio of height to diameter, including power consumption, shear preformance, axial pumping and mixing time, is studied on the ba-sis of computational fluid dynamic ( CFD) simulation in Non-newtonian pseudoplastic fluid. The power consump-tion, shear performance, axial pumping and mixing time. The results indicate that in a certain range, the impeller has high shear rate and…查看全部>>
