On Blockage Effects for a Tidal Turbine in Free Surface Proximity
Energies, 2019 Experiments with a three-bladed, constant chord tidal turbine were undertaken to understand the influence of free surface proximity on blockage effects and near-wake flow field.

A Joint Precoding Framework for Wideband Reconfigurable Intelligent Surface-Aided Cell-Free Network [PDF]
IEEE Transactions on Signal Processing, 2020 Thanks to the strong ability against the inter-cell interference, cell-free network is considered as a promising technique to improve network capacity. However, further capacity improvement requires to deploy more base stations (BSs) with high cost and ...

Free Surface Characteristics of Flow around Two Side-by-Side Circular Cylinders
Journal of Marine Science and Engineering, 2018 The three-dimensional free surface characteristics of flow around two equal diameter cylinders in a side-by-side arrangement were studied numerically. The flow fields were simulated with a three-dimensional finite volume method based on the RNG k-ɛ model

Coating Flow Near Channel Exit. A Theoretical Perspective
Fluids, 2020 The planar flow of a steady moving-wall free-surface jet is examined theoretically for moderate inertia and surface tension. The method of matched asymptotic expansion and singular perturbation is used to explore the rich dynamics near the stress ...

Free Surface Ductility in Upsetting
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1991 Surface cracking in upsetting is investigated with the analytical method based on the modified criterion for the collapse of unique solution, and the modes of cracking are determined by comparing the stabilities of deformation from the forming limit to the two modes able to permit strain rate discontinuity on the plane of localized necking. The forming

Incoherence of free-by-free and surface-by-free groups
, 2020 There is an error in the proofs of Theorem 3.1 and Theorem 3.5 which we cannot immediately fix. We thank Hongbin Sun for pointing this error out. We are merging the results on groups which do not virtually algebraically fiber (which are unaffected by this error) with our paper arXiv:2103 ...

Air flow effect on the behavior of lock-exchange gravity current [PDF]
Journal of Hydraulic Structures, 2020 The main goal of this study is investigating the effect of air flow above the free surface on the behavior of gravity current. Lock-release gravity current has been simulated in a channel, by using VOF method, for modeling free surface at the interface ...
