Dr Ke Wu
Postdoctoral Researcher

Ke Wu is a postdoctoral researcher in I-Form at UCD. He completed his PhD in Computational Modeling of Fluid-Solid Interaction Problems by Coupling Smoothed Particles Hydrodynamics and the Discrete Element Method in the School of Civil Engineering, University of Leeds. He received undergraduate and master’s degrees in mechanical engineering from University of Sheffield and Imperial College London, respectively. His current research interests lie in computational engineering (multi-scale, multi-physics, multiphase coupling).

Research Interests (Lay Summary)

Ke Wu has been working in the area of developing a computational platform to encompass and interface algorithms for multi-physics, multi-scale additive manufacturing (AM) modeling. This involves development of a common computational platform within OpenFOAM, with customised data interfaces to directly predict key AM microstructure attributes, global mechanical and damage/fracture/fatigue properties, and local and global residual stresses of AM components.

 

Technical Summary

Ke Wu is developing a computational platform involving multi-scale coupling of macro-scales thermal CFD, meso-scale granular zones and micro-scale CA and PFM, resulting in a three-scale system. Both hierarchical and embedded coupling procedures will be developed to achieve high local accuracy using the embedded approach (where required) and efficiency using the hierarchical approach. Each computational procedure within the platform will be ‘locally’ validated. AM processes will be simulated and the structure-property predictions will be rigorously verified both in terms of measured properties and geometrical quality.
