Understanding flow accelerated corrosion of pumps used in net-zero energy applications

该博士学位将与苏尔寿合作，在代表净零能量应用的条件下研究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寿命，在能源转换应用中普遍存在（例如碳捕获和储存，地热能）。由于在净零能量应用的基础设施（例如泵）中遇到的复杂流体动力学，对流动加速腐蚀的了解很少。流体力学和流动加速腐蚀之间的明确关系将通过结合定制的流动池实验和计算流体动力学（CFD）模拟来确定流体流动行为。通过设计一个定制的高速流动池，与电化学传感集成，可以进行空间分辨腐蚀测量，以了解材料降解。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，并建立腐蚀和流动之间的关系。

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.
