摘要：In this work, we investigate numerical solutions ofthe moisture transport in rough rice. In Thailand, moisturecontent of rough rice is one of the most important factorsfor setting price of rough rice. In computational method, themoisture transport in rough rice can be considered as an infinitecylinder. The model can be discribed by the diffusion equationwith a convective boundary condition. The explicit and implicitschemes of finite difference methods are applied to solve suchthe problem. The numerical results show that the moisturecontent is distributed from centre to boundary surface of therough rice. The numerical simulations of the moisture contentat various radius are also illustrated.
