【摘要】 为了验证粮仓通风CFD模型的结果以促进计算流体力学技术在粮食储藏技术中的应用,本研究开发了针对粮仓通风地槽的模型试验理论和技术,并进行了实仓检测与通风效能对比。研究表明,试验数据与CFD模型计算相互印证,能充分反映风道的整体通风性能和粮堆的降温特征,能够成为今后研究粮仓通风系统效能的有效方法。更多还原

【Abstract】 To validate the CFD result of numerical model of grain storage mechanical ventilation,so as to enhance the application of CFD technology in the study of grain storage,a state-of-art theory and technology of model test is developed in this study,and the in-site measurement with ventilation efficiency comparison study is done as well.It is showed that the experiment data can well mirror the result with CFD method,in which the overall ventilation performance of ventilation trough and temperature field of grain storage are reflected with detail.The combination of CFD and model test could be used as an effective tool to investigate the ventilation system for grain storage in the future.更多还原
