RISUnit-Based Design of Cross-Flow Heat Exchangers for LPBF Additive Manufacturing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The structural design and additive manufacturing (AM) of cross-flow heat exchangers (HXs) are studied. A unit-based design framework is proposed to optimize the channel configuration in order to improve the heat exchange ...
A Theoretical Contact Model for Rough Elastic Spheres
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Investigating the contact of rough spheres is constructive to wide engineering applications and scientific research. However, the coexistence of global curvature and surface roughness brings difficulty in the analysis of ...
A Modified Simulated Annealing-Based Method for Hybrid Lattice Support Structure Design in LPBF Additive Manufacturing
Publisher: The American Society of Mechanical Engineers (ASME)
