FIDELITY MODELLING POWDER BASED ADDITIVE

项目摘要

This 2-year project aims to increase the processibility of recycled powders and powders with aspherical grains in powder-based Additive Manufacturing (PBAM) process or 3D printing. This will be achieved by extending a state-of-the-art computational framework, developed at the Host institution, to provide the ability to model a full cycle of the process. Therefore, the fellow will (1) establish a novel procedure for incorporating the powder characterisation data obtained at temperatures exceeding 500C, equivalent to those experienced in the PBAM build chamber; (2) develop a new ray-tracing model to accurately predict laser absorption in fine powders; (3) develop an accurate model to predict the powder melting and evaporation; (4) pinpoint the impact of grain shape on melt-pool dynamics to allow for aspherical grains while maintaining the powder processability (5) engage with industrial and academic research partners to ensure wide adoption of the developed models. The impact of the project is far-reaching: from reducing the costs of raw material for PBAM to increasing public awareness of the utility of high-performance computing (HPC) in solving complex scientific/engineering problems. The success of the project is ensured by bringing together a competent team of academics and engineers with complementary multidisciplinary skills at UEDIN and the host's network of academic and industrial partners who will work with the applicant to provide a ground-breaking solution to this research challenge. The timely award of this fellowship will help the applicant to develop his skills to pioneer this line of research independently and build his own globally competent research team.

这个为期 2 年的项目旨在提高粉末增材制造 (PBAM) 工艺或 3D 打印中回收粉末和非球形颗粒粉末的可加工性。这将通过扩展主办机构开发的最先进的计算框架来实现，以提供对整个过程周期进行建模的能力。因此，该研究员将 (1) 建立一种新颖的程序，用于合并在超过 500C 的温度下获得的粉末表征数据，相当于 PBAM 构建室中所经历的数据； (2) 开发新的射线追踪模型，以准确预测细粉末中的激光吸收； (3)建立准确的模型来预测粉末的熔化和蒸发； (4) 查明晶粒形状对熔池动力学的影响，以允许非球形晶粒，同时保持粉末可加工性 (5) 与工业和学术研究合作伙伴合作，确保所开发的模型得到广泛采用。该项目的影响是深远的：从降低 PBAM 原材料成本到提高公众对高性能计算 (HPC) 在解决复杂科学/工程问题中的效用的认识。 UEDIN 汇集了一支由具有互补的多学科技能的学者和工程师组成的优秀团队，以及东道主的学术和工业合作伙伴网络，这些合作伙伴将与申请人合作，为这一研究挑战提供突破性的解决方案，从而确保了该项目的成功。该奖学金的及时授予将帮助申请人培养独立开拓这一研究领域的技能，并建立自己的具有全球竞争力的研究团队。
