Rubber glove manufacturing requires improvements in the curing process. In this study, the forced convection of hot airflow past a hand-shaped former, which has a typical shape in the rubber glove manufacturing process, was examined. A former model consisting of five fingers, palm, dorsum, and wrist was separated to investigate the convective heat transfer of the individual parts by OpenFOAM. The study conditions for the manufacturing process were a Reynolds number ranging from 15,837 to 63,351 and an angle of attack from 0° to 180°. After validating the computational fluid dynamics models with experiments and previous research, the k–ω shear stress transport turbulence model was appropriate. The angle of attack slightly affected the average Nusselt number on all parts of the hand-shaped former except the dorsum. An optimization method was employed to determine the optimal attack angle that caused the maximum convective heat transfer. The result was 0°. Therefore, the simulation results for the dorsal part at 0° established an average Nusselt number equation. This equation had an accuracy with an average error of less than 0.24% and an R² of 0.9997. The average Nusselt number equation of the dorsal part is representative for analyzing the heat transfer in the curing process in rubber glove manufacturing.

橡胶手套制造需要改进固化过程。在这项研究中，研究了热气流通过手形成型器的强制对流，该成型器在橡胶手套制造过程中具有典型形状。将由五个手指、手掌、背部和手腕组成的前模型分开，以研究 OpenFOAM 各个部分的对流热传递。制造过程的研究条件是雷诺数从 15,837 到 63,351，攻角从 0° 到 180°。通过实验和先前的研究验证计算流体动力学模型后，k - ω剪应力传递湍流模型是合适的。攻角对除背部以外的手形模型所有部位的平均努塞尔数有轻微影响。采用优化方法来确定导致最大对流传热的最佳攻角。结果是0°。因此，背侧0°处的模拟结果建立了平均努塞尔数方程。该方程具有小于 0.24% 的平均误差和0.9997的R ^{2的准确度。}背部的平均努塞尔数方程代表橡胶手套制造中固化过程中的传热分析。
