Contributions to the Understanding of Turbulent Boundary Layers Over Curved Walls
<p>A wind tunnel campaign was conducted to investigate the DARPA Suboff boundary layer. To emphasize the axisymmetric boundary layer, the generic submarine model's sail, appendages, and propeller were omitted. The study focused on the afterbody from 70–95% of the model length to examine the …

Design computing of complex-curved geometry using digital fabrication methods
… construction as architectural models of complex curved walls built from unique units. A series of computer programs and physical models as examples of orthogonal, non-orthogonal, and complex curved walls as designs were developed. The wall examples here are built of non-uniform, interlocking …

An examination of flow characteristics in collapsing elastic tubes
… and to the post-collapse shape of the models (curved walls and non-circular cross-section). Time-exposed photographs of tracer particle displacements within the model indicate increased volumetric flow in each branch during the initial phase of the collapse process. Moreover, it was seen that …

Light interaction
… reveal a building halfway up. Its thick, rough walls are pulled apart at moments, allowing light and movement into the space. The path leads between the walls. The narrow passage continues in a counter-clockwise motion up a staircase, leading you towards the light; moving from opacity to …

A multiscale mechanobiological investigation of scaffold designs for bone tissue engineering
… into features larger than 100 μm, such as curved walls and struts, generating porous scaffold architectures with maximal abundance of mechanical microenvironments thought to be osteogenically favorable. To enable consideration of both material and structure together, an agent-based model …

A methodology for coupled CFD-DEM modeling of particulate suspension rheology
… with a 500μm gap between the inner and outer walls was found to perform the best. Final CFD model parameters used in these simulations were used as the basis for the coupled model. To reduce computational complexity, the model size and shape had to be reduced from a full-sized rheometer to …

Structural Design Inspired by the Multiscale Mechanics of the Lightweight and Energy Absorbent Cuttlebone
… including the 3D asymmetric shape of individual walls, the wall assembly patterns, and the long-range structural gradient of walls across the entire cuttlebone (ca. 40 chambers). The acquired 3D structural information enables systematic finite-element simulations, which further reveal the …
