The process of wood-drying consumes energy more than necessary for evaporation of moisture. The CFD technique with the Finite Volume Method is applied to the flow analysis in narrow channels of pile-up arrangements in the steam-heated dry kiln. Most of energy supplied from the internal funs is converted to kinetic energy of flow velocities circulating around the pile-up arrangements in the kiln. The influence of flow adjuster plates on the flow is showed numerically, and proposals for better configuration of adjuster plates are made. Furthermore, flow control plates on the floor of the kiln make effective improvements on the flows in narrow channels of pile-up arrangements.
