Heat and Mass Transfer in a Paper Sheet During Drying Creativity Award

从农业到塑料，几乎所有主要行业都使用干燥工艺，但效率只有40-45%。一个先进的干燥系统模型，在一个用户友好的软件格式，可以帮助在纸浆和造纸工业的情况下，在整个系统效率和干燥滚筒的设计和维护。虽然在讨论多孔介质的传热和传质方面有很多工作，但很少有针对纤维介质和除水系统的模型。一般来说，现有的模型要么包含了太多的假设，要么无法与实验数据相关联。这项研究的目的是建立一个合适的模型，一旦通过可接受的假设和近似值进行简化，就可以进行数值求解。然后将开发一个软件包来模拟整个干燥系统。

Drying processes are used in almost all major industries from agriculture to plastics, yet are only 40-45% efficient. An advanced model for a drying system, presented in a user-friendly software format, could aid in both overall system efficiency and in the design and maintenance of the drier drums in the case of the pulp and paper industry. Although much work is available discussing heat and mass transfer through porous media, very few models have been developed for fibrous media and water removal systems. In general, existing models either incorporate too many assumptions or else fail to correlate with experimental data. %%% The intent of this research is to develop a suitable model which, once reduced by acceptable assumptions and approximations, can be solved numerically. A software package will then be developed to simulate entire drying systems.
