采用瞬态线热源法测定了两种硬粒小麦和一种小麦产品干小麦在不同水分含量和环境温度下的有效导热率。样品的湿基含量为 9.17% 至 38.65%，堆积密度为 675 至 827 kg/m3。在这些条件下，测得的有效导热系数范围为 0.159 至 0.201 W/m.K。发现有效导热率随水分含量线性增加。结果也与文献值非常吻合。
The effective thermal conductivity of two varieties of Triticum durum wheat and a wheat product, bulgur, is determined at different moisture contents and at ambient temperature by the transient line heat source method. The moisture contents of the samples ranged from 9.17 to 38.65 percent wet basis and the bulk densities ranged from 675 to 827 kg/m3. Under those conditions, the measured effective thermal conductivities ranged from 0.159 to 0.201 W/m.K. The effective thermal conductivity is found to be linearly increasing with moisture content. The results are also in good agreement with literature values.
