摘  要:
利用流体力学相似原理及模型试验的方法,以传统的U型地槽平仓房为原型,设计了平仓房机械通风储粮的模型实验台。以大米为研究对象,通过对模型实验台进行通风实验和对各个监测点温度变化的分析,发现了与实际现象相符的通风死角的发生区域,从而验证了模型试验的可行性。

摘  要:
According to the principle of similarity in the hydrodynamics and model test method,a traditional flat barn with u-shaped geosyncline was used as prototype to design the model test bench of mechanical ventilation in flat barns for grain storage.Using rice as the study subject,through conducting ventilation experiment for the model test bench and analyzing the temperature change in each individual monitoring-station,the dead corner of ventilation,which matching to the practical phenomenon,was found out.Thus,the feasibility of the model test was verified.
