摘　　要：为了探究开式和闭式2种气流循环模式热泵密集烤房在烟叶烘烤过程中内流场的变化,通过计算流体力学(CFD)方法对2种气流循环模式的烤房在不同烘烤阶段其装烟室内部风速场和温度场进行了仿真模拟。结果表明:模拟开式与闭式热泵密集烤房装烟室内风速场差异不明显,2种类型烤房装烟室内整体风速分布均匀,热空气流动性较好;模拟开式和闭式热泵密集烤房装烟室内温度变化范围均适宜,整体温差较小,模拟闭式热泵密集烤房装烟室内温度均匀性优于开式。综上所述,在对密集烤房内流场进行研究时采用CFD方法具有可行性与实用性,分析模拟的不同气流循环模式热泵密集烤房内流场对实际生产中烤房类型选择能够提供理论支持,对提高烟叶烘烤效果有一定意义。In order to investigate the changes of the internal flow field in the heat pump bulk curing barns with open and closed airflow circulation modes during the flue-curing process of tobacco leaves,the air velocity field and temperature field inside the tobacco loading chamber of the curing barn with two airflow circulation modes in different flue-curing stages were simulated by computational fluid dynamics(CFD)method.The results showed that the difference of air velocity fields inside the tobacco loading chamber between the simulated open and closed heat pump bulk curing barns was not obvious,and the overall air velocity distribution in the tobacco loading chamber of both types of curing barns was uniform,and the hot air mobility was good.The range of temperature variation in the tobacco loading chamber of the simulated open and closed heat pump bulk curing barns was suitable,the overall temperature difference was small,and the temperature uniformity in the tobacco loading chamber of the simulated closed heat pump bulk curing barn was better than that of the open type.In summary,the CFD method is feasible and practical for studying the internal flow field in the bulk curing barn.The analysis on the simulated internal flow field in the heat pump bulk curing barns with different air circulation modes can provide theoretical support for the selection of barn types in actual production and has certain significance for improving the flue-curing effect of tobacco leaves.
