摘要
温度是生物培养生长过程中的重要影响因素,为了研究培养箱温度均匀性情况,对培养箱内温度场进行分析。首先基于Fluent软件对培养箱内空气流动进行三维数值模拟,分别对有CO_(2)检测模块、无CO_(2)检测模块和CO_(2)检测模块圆角化3种情况下的培养箱进行温度场仿真,然后对仿真所得结果进行分析。结果显示:无CO_(2)检测模块温差小于有CO_(2)检测模块;有CO_(2)检测模块会使得总体温差有所增大;CO_(2)检测模块圆角化后总体温度差减小,可以抵消有CO_(2)检测模块带来的温差增大。因此CO_(2)检测模块圆角化时温度场最均匀。3种培养箱结构的仿真分析结果为后续培养箱结构优化和研究提供了良好的技术支持。
Temperature is an important factor in the growth process of biological culture.In order to study temperature control of the incubator,the temperature field in the incubator was analyzed,conductingthe 3D numerical simulation of the air flow in the incubator by means of Fluent software.Firstly,the temperature field simulation was performed on the three cases of CO_(2) detection module,no CO_(2) detection module and CO_(2) detection module rounding,and then the simulation results were analyzed.The results show that the temperature difference with no CO_(2) detection module is smaller than that with CO_(2) detection module;the presence of CO_(2) detection module tends to increase the overall temperature difference;rounding tends to decrease the overall temperature difference,which can offset the increase in temperature difference caused by the presence of CO_(2) detection module.Therefore,the temperature field is the most uniform when the CO_(2) detection module is rounded.The simulation analysis results of the three incubator structures provide a sound technical solution for the subsequent optimization and research of the incubator structure.
