桨叶结构参数对双行星搅拌混合过程的模拟影响OA北大核心CSTPCD

A 3 L dual planetary mixer for lithium-ion battery slurry was investigated,focusing on how blade structural parameters like helical angle and gap size impact mixing performance.The k-s model and dynamic mesh simulations were employed.It finds that these parameters significantly influence the mixer's cyclic,shearing,and power characteristics.An increase in the helical angle improves axial circulation but decreases radial circulation,while a smaller gap boosts shearing performance and power consumption.Among the three mixing performance evaluation indicators,shearing performance is the most significantly affected,with the influence of the structural parameters on shearing characteristics in the order of blade helical angle＞blade gap.Through orthogonal test analysis,the optimal combination is a blade helical angle of 50° and a blade gap of 6 mm.
