This PhD will investigate flow accelerated corrosion of cast iron and carbon steel pump components in conditions representative of net-zero energy applications, in collaboration with Sulzer. Flow accelerated corrosion critically limits the lifespan of flow system components, being prevalent across energy transition applications (e.g. carbon capture and storage, geothermal energy). Due to the complex hydrodynamics that are encountered in the infrastructure of net-zero energy applications, e.g. pumps, flow accelerated corrosion is poorly understood. A clear relationship between hydrodynamics and flow accelerated corrosion will be established through the combination of experiments in bespoke flow cells and computational fluid dynamics (CFD) simulations to characterise fluid flow behaviour. By designing a bespoke high velocity flow cell, integrated with electrochemical sensing, spatially resolved corrosion measurements can be performed to understand material degradation. Combining experimental data with CFD simulations of the flow will enable hydrodynamic parameters to be extracted and a relationship between corrosion and flow to established.

该博士将与Sulzer合作，研究在代表净零能耗应用的条件下，铸铁和碳钢泵部件的流动加速腐蚀。流动加速腐蚀严重限制了流动系统部件的使用寿命，在能源转换应用(如碳捕获和储存、地热能)中普遍存在。由于在净零能耗应用的基础设施(如泵)中遇到的复杂流体动力学，人们对流动加速腐蚀知之甚少。流体力学和流动加速腐蚀之间的明确关系将通过在定制流动池中的实验和计算流体动力学(CFD)模拟相结合来描述流体流动行为。通过设计一种定制的高速流动池，结合电化学传感，可以进行空间分辨腐蚀测量，以了解材料的降解情况。将实验数据与流动的CFD模拟相结合，将能够提取流体动力学参数，建立腐蚀与流动之间的关系。
