Modelling and industrial application of flow through two-dimensional porous media

[摘要] ENGLISH ABSTRACT:A Representative Unit Cell (RUC) model for flow through two-dimensional porous media ispresented and applied to two industrial related problems. The first application is to that ofcross-flow in tube banks. Both staggered and square (inline) configurations are investigatedand the model results are compared to experimental data. The second application is to flowthrough a stack in a timber-drying kiln. The RUC model is applied to the anisotropic timberstack ends and the centre part is modelled with a standard duct flow solution. The resultsof the models applied to a timber stack are compared to experimental data obtained frommodel tests undertaken in a wind tunnel. The results of the RUC and duct flow models arefound to be in excellent agreement with the data of the experimental models. These modelsmay be used to optimize kiln designs.
