Özet
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/m(3). 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. (C) 1998 Elsevier Science Ltd.
