摘　　要：隧道式速冻机广泛应用于食品加工行业,其效率和性能直接影响产品的质量和生产成本。为了探究Y型喷嘴结构尺寸对速冻机内部流场的影响,建立七种不同尺寸的Y型喷嘴模型,使用计算流体动力学方法(COMSOL软件)进行数值模拟,并通过实验加以验证,分析了喷嘴开口大小对出口风速、压力分布和对流热通量的影响。结果表明,随着喷嘴开口的增大,出口风速和对流热通量显著提高,其中开口为78 mm的喷嘴性能最佳。研究结果为优化Y型喷嘴设计提供了理论依据,有助于提高隧道式速冻机的性能和效率。Tunnel freezers are widely used in the food processing industry,where their efficiency and performance directly impact product quality and production costs.To investigate the influence of Y-shaped nozzle structural dimensions on the internal flow field of quick-freezing machines,seven Y-shaped nozzle models with different dimensions were constructed.Numerical simulations were conducted using Computational Fluid Dynamics(COMSOL software),and the results were validated through experiments.The study analyzed the effects of nozzle opening size on outlet wind speed,pressure distribution,and convective heat flux.The results indicate that as the nozzle opening increases,the outlet wind speed and convective heat flux significantly improve,with the 78mm opening nozzle exhibiting the best performance.The findings provide a theoretical basis for optimizing Y-shaped nozzle design,contributing to the enhancement of tunnel freezer performance and efficiency.
