15 صفحه اولReliability of One Dimensional Model of Moisture Diffusion in Wood
A model of the moisture diffusion in wood under isothermal conditions taking into consideration coating of the surface of a specimen is presented in a 2-D-in-space formulation. A reliability of a corresponding 1-D model is investigated for a simulation of moisture movement in 2-D medium. This paper presents a technique to determine the width as well as the degree of edges coating of the specime...
متن کاملDependence of hillslope moisture content on downhill saturation
We derive steady equilibria for lateral downslope moisture flow in an ide-alized thin closed layer as a solution to the 1D Richards' Equation. The equilibria are determined by two free parameters: the downslope flux and a boundary condition. Solutions exhibit a constant downslope flow speed and moisture content for the constant equilibrium flux, which is the product of the two. However where an...
متن کاملTemperature and concentration dependence of diffusion coefficient in dilute solutions*
Temperature and molecular weight dependence of k o in D(C)=D(O)[1 +CkD], where D(C) is the diffusion coefficient for the density fluctuations in a dilute polymer solution, is investigated by first expressing D(C) as a function of the static structure factor S(q,C) within the framework of the Kirkwood-Riseman theory. The continuous transition of k D from negative values under theta conditions to...
