摘要: 提高烤房内温度及气流组织分布的均匀性,不仅可有效提高烟叶烘烤质量,而且可在一定程度上缩短烘烤时间,从而降低烘烤能耗。以密集型标准烤房为模拟研究对象,建立了装烟室内空气流动的k-ε两方程三维紊流模型。利用大型计算流体力学软件Fluent,对密集烤房内温度场及速度场进行了系统地数值模拟。分析了装烟室内温度及气流分布的均匀性,并获得了密集烤房合理的送风量。相关的数值模拟结果可为密集烤房结构、气流组织分布优化及循环风机选型提供参考。

Abstract: By enhancing the uniformity of the temperature and velocity fields’ distribution in curing barn, the quality of flue-cured tobacco effectively can be improved, and the curing time can be shortened to some degree, therefore, the energy consumption of curing can be reduced. Taking the standard bulk curing barn as the investigated subject, the model of air flow in curing barn with k-ε three-dimension two equations turbulent flow was established. Based on the large software of Fluent within computation fluid dynamics, the numerical simulation of the temperature and velocity distribution in curing barn was conducted in detail. The reasonable supply air volume for bulk curing barn was obtained. The results of numerical simulation could be used for the structure design of bulk curing barn, the temperature and velocity distribution optimization and the selection of circulation fan.
