小麦秸秆砌块温度场的数值模拟

我国农业生产中大量的秸秆利用率低,浪费了宝贵的生态资源,小麦秸秆砌块作为新兴墙体材料有广阔的发展前景。采用2D轴对称模型来模拟小麦秸秆砌块在导热过程中的温度场,采用ADINA有限元软件作为模拟工具。分析结果表明,小麦秸秆砌块在保温隔热性能方面具有显著优势。

Numerical simulation of temperature field on wheat straw block

The utilization of the massive straw stalk in our country angricultural is low,which wastes the precious ecology resources,so the wheat straw stalk as a new emerging wall material has the broad prospects for development。This article uses the 2D symmetric model to simulate the temperature field of the wheat straw stalk in heat condution by the ADINA finite element software。The analysis result indicated that the wheat straw stalk has the remarkable superiority in the aspect of heat insulation properties。
