Advanced Materials Technologies, EarlyView.This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Oscillation characteristics of mutually impinging dual jets in a mixing chamber
The Physics of Fluids, 2018 In this study, we consider the oscillatory behavior of mutually impinging jets in an enclosed, dome-shaped mixing chamber. The frequency of the impinging jet oscillations is dictated by the flow rate, with the oscillatory behavior being grouped into ...

Hydrodynamics of long jet impingement [PDF]
WIT Transactions on Engineering Sciences, 2008 A circular turbulent long jet has been assessed numerically using the volume-of-fluid method to examine the hydrodynamics of a long jet before impingement and to inspect the flow structure of a radial thin layer spreading over a flat plate after impingement. Typical steel mill industrial parameters are used in the model.

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

Flow Asymmetry in Symmetric Multiple Impinging Jets: A Large Eddy Simulation Approach
The Journal of Engineering Research, 2011 A numerical study on in-line arrays of multiple turbulent round impinging jets on a flat heated plate was conducted. The Large Eddy Simulation turbulence model was used to capture details of the instantaneous and mean flow fields.

Rarefied planar jet and jet impingement flows [PDF]
AIP Conference Proceedings, 2012 This paper presents three sets of analytical exact solutions to collisionless gas flows from a two-dimensional exit. The first set is free plume expanding into a vacuum, and the other two sets are collisionless plume impingement at a vertically set plate.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
