| 内容記述 | The method of evaluation of the heat -, and the water vapor transfer coefficients in the field has been investigated. By this means, the drying rate of soil can be assessed according to the heat transfer tbeory. To calculate these coefficients, the amounts of the heat and the water vapor exchanged between the atmosphere and soil surface must be estimated, in addition to the differences in temperature and humidity between them. First, various methods have been derived analytically to calculate the thermal constants of soil, the temperature and the heat flux at soil surface by using temperature variations not only in uniform but also in non-uniform soil. Then, procedure for evaluating the transfer coefficients was presented by substituting those amounts into the heat balance equation at soil surface. The above procedures were applied to the indoor experimental data on the drying from the wet soil columns, and the field data on the condition with the dry soil surface layer. For the soil columns, the drying rates assessed from the transfer coefficients agreed well with the data obtained by the weight changes. In case of the dry soil surface, humidity at the surface was difficult to measure. However the inferencial error of this value was found to have little effect on the results of the drying rate assessed from the transfer coefficients during a high drying rate. | |||||||||
