Numerical investigation of fluid-solid interaction for flow around three square cylinders

AIP Advances, 2018
In this work, fluid-solid interactions are numerically investigated for flow around three equally/unequally spaced square cylinders using the lattice Boltzmann method. Two major trends of shear layers observed for equal gap spacings between cylinders: (i)

Vanishing of local non-Gaussianity in canonical single field inflation

, 2018
We study the production of observable primordial local non-Gaussianity in two opposite regimes of canonical single field inflation: attractor (standard single field slow-roll inflation) and non attractor (ultra slow-roll inflation).

Maskless Electrochemical Texturing (MECT) Applied to Skin-Pass Cold Rolling

Lubricants
The surface topography of the rolls used in skin-pass cold rolling determines the surface finish of rolled sheets. In this sense, work rolls can be intentionally textured to produce certain topographical features on the final sheet surface.

Compaction Behavior of Isomalt after Roll Compaction

Pharmaceutics, 2012
The suitability of the new isomalt grade galenIQ™ 801 for dry granulation and following tableting is evaluated in this study. Isomalt alone, as well as a blend of equal parts with dibasic calcium phosphate, is roll compacted and tableted ...

STRIP ROLLING MILL’S FLEXIBLE MULTI-BODY SYSTEM COUPLING DYNAMIC MODELING RESEARCH

Jixie qiangdu, 2019
During the rolling process, the rolling mill’s working stability is determined by the system’s dynamic characteristics. Among which, the roll system’s rigid motion and the work roll and backup roll‘s flexural deformation movement are the main factors ...

A Holistic Review of Surface Texturing in Sheet Metal Forming: From Sheet Rolling to Final Forming

Lubricants
Skin-pass cold rolling is a crucial step in sheet metal production, modifying the sheet surface topography, ensuring thickness uniformity, and enhancing tribological performance. A key factor in this process is the surface texturing of work rolls, which,
