Cleaning is a critically important operation in the food, pharmaceutical and other sectors. Many cleaning in place (CIP) systems employed in manufacturing industry rely on the flow of cleaning solutions or solvents to achieve removal of the soiling layer. It would be highly desirable to be able to predict the cleanability of an item of process equipment or a production line at the design stage, so that plant and CIP processes can be designed for efficient cleaning. The potential impact is significant: cleaning consumes large quantities of fresh, potable water as well as thermal energy and chemicals, all of which influence the financial and ecological sustainability of food manufacturing operations. Advances in computational fluid dynamics (CFD) methods mean that the flow behaviour can be estimated with good levels of accuracy for many of the geometries and flow configurations which arise in practice. The link to cleanability lies in the rheology of the deposit and how it responds to the forces imposed by the fluid both instantaneously and over time. This project brings together expertise in CFD (Prof. Cant) with rheology (Prof. Wilson) to develop methods for predicting the cleaning performance of a range of food types.

清洁是食品、制药和其他行业中至关重要的操作。制造业中使用的许多就地清洗 (CIP) 系统依靠清洗溶液或溶剂的流动来实现污垢层的去除。非常希望能够在设计阶段预测工艺设备或生产线的可清洁性，以便可以设计工厂和 CIP 工艺以实现高效清洁。潜在的影响是巨大的：清洁消耗大量的新鲜饮用水以及热能和化学品，所有这些都会影响食品制造业务的财务和生态可持续性。计算流体动力学 (CFD) 方法的进步意味着对于实际中出现的许多几何形状和流动配置，可以高精度地估计流动行为。与清洁性的联系在于沉积物的流变性以及它如何响应流体瞬时和随时间施加的力。该项目汇集了 CFD（Cant 教授）和流变学（Wilson 教授）方面的专业知识，开发预测一系列食品类型清洁性能的方法。
