| 为提高空化射流均质大豆蛋白溶液的能力，设计了一种多级空化均质喷嘴。利用分形理论建立颗粒粒径与流体的压强、流速的关系，在此基础上采用空化射流计算流体力学（CFD）仿真方法，对多级空化均质喷嘴的空化过程进行模拟仿真，以空化前后大豆蛋白溶液的单位质量能量变化量为考察指标，利用响应面法对风琴管空化均质喷嘴结构参数（收缩段直径、收缩段长度和扩散段长度）进行优化。结果表明：优化的喷嘴结构参数为收缩段直径0.5 mm、收缩段长度6 mm和扩散段长度8 mm，在此条件下单位质量能量变化量达到10 972 J/kg，经理论计算检验，均质后大豆蛋白溶液的颗粒比表面积增大，粒径明显降低，平均颗粒粒径小于285 nm；在优化的喷嘴结构参数下进行仿真，根据仿真数据计算得到的单位质量能量变化量为11 056.98 J/kg，与回归模型预测值误差仅为0.77%。综上，优化设计的多级空化均质喷嘴可有效减小大豆蛋白溶液颗粒粒径和增大比表面积，有利于提升大豆蛋白溶液的加工性能，提高大豆蛋白溶液的处理效率。 |

| To enhance the ability of cavitation jet to homogenize soybean protein solution, a multistage cavitation homogenization nozzle was designed. Using fractal theory, a relationship between particle size and fluid pressure and velocity was established. Then the cavitation process of the multistage cavitation homogenization nozzle was simulated by employing the cavitation jet CFD simulation method, and the response surface methodology was used to optimize the structural parameters of the organ tube cavitation homogenization nozzle (contraction section diameter, contraction section length and diffusion section length) by taking the energy change per unit mass of the soybean protein solution before and after cavitation as an investigation index. The results showed that the optimized nozzle structure parameters were contraction section diameter 0.5 mm, contraction section length 6 mm and diffusion section length 8 mm, under which the energy change per unit mass reached 10 972 J/kg. The theoretical calculations showed that the specific surface area of the particles of the homogenized soybean protein solution increased, the particle size significantly decreased, and the average particle size was less than 285 nm. Simulation was carried out under the optimized nozzle structural parameters, and the energy change per unit mass calculated from the simulation data was 11 056.98 J/kg, with an error of only 0.77% from the regression model prediction. In conclusion, the optimized multistage cavitation homogenization nozzle can effectively reduce the particle size and increase the specific surface area of the soybean protein solution, thereby improving its processing performance and enhancing treatment efficiency. |
