Numerical Simulation and Optimization of Flow and Temperature Fields in a Novel Shoe Glue Tunnel Drying Equipment Based on Ansys Fluent

摘要: 针对传统制鞋流水线中鞋胶烘干工序因内部流场无序导致的受热不均、局部脱胶与热能利用率低等痛点，探究受限隧道空间内空气动力学布局对热活化质量的底层影响机理。文章以一款新型空气能热泵鞋胶烘干设备为研究对象，采用计算流体力学(CFD)软件Ansys Fluent对其内部流场与温度场进行三维稳态与瞬态数值模拟。建立多面体网格模型，选取Realizable k-ε湍流模型，对比分析了同侧单向流与优化结构异侧环形流的流热耦合特性。通过对气动拓扑结构进行重构，将出风口与回风口交错布置于传送带两侧，在隧道内部激发涡旋环形流场，增强了受限空间内的对流换热效率与温度场均匀性。仿真数据与热线风速仪实测数据(误差 < 5%)高度吻合，验证了模型的可靠性，为制鞋烘干装备的研发与流道设计提供了科学的理论依据。

Abstract: Addressing the pain points of uneven heating, localized degumming, and low thermal energy utilization caused by disordered internal flow fields in the shoe glue drying process of traditional shoe manufacturing production lines, this paper explores the underlying mechanism of the aerodynamic layout within a confined tunnel space on the quality of thermal activation. A novel air-source heat pump shoe glue drying equipment is used as the research object. Three-dimensional steady-state and transient numerical simulations of its internal flow and temperature fields are conducted using the computational fluid dynamics (CFD) software Ansys Fluent. A polyhedral mesh model is established, and a Realizable k-ε turbulence model is selected. The fluid-thermal coupling characteristics of unidirectional flow on the same side and annular flow on the opposite side of the optimized structure are compared and analyzed. By reconstructing the aerodynamic topology and staggering the air outlets and return air inlets on both sides of the conveyor belt, a vortex-like annular flow field is generated inside the tunnel, enhancing the convective heat transfer efficiency and temperature field uniformity within the confined space. Simulation data and measured data from a hot-wire anemometer (error < 5%) show high agreement, verifying the model’s reliability and providing a scientific theoretical basis for the research and development and flow channel design of shoe drying equipment.
