CFD Simulation of Transonic Flow in High-Voltage Circuit Breaker

open access: yesInternational Journal of Chemical Engineering, 2012
A high-voltage circuit breaker is an indispensable piece of equipment in the electric transmission and distribution systems. Transonic flow typically occurs inside breaking chamber during the current interruption, which determines the insulating ...

The role of fluid flow in the dynamics of active nematic defects

open access: yesNew Journal of Physics, 2021
We adapt the Halperin–Mazenko formalism to analyze two-dimensional active nematics coupled to a generic fluid flow. The governing hydrodynamic equations lead to evolution laws for nematic topological defects and their corresponding density fields.

Theoretical prediction of interference loading on aircraft stores: Part I - Subsonic speeds [PDF]

open access: yes, 1973
Computer program is developed for theoretically predicting loading on pylon-mounted stores in subsonic compressible flow. Linear theory predicts flow field produced by aircraft wing, nose, inlet, and pylons. Program was written in FORTRAN IV for CDC 6000

Motion of slightly compressible fluids in a bounded domain. II

open access: yes, 2016
We study the problem of inviscid slightly compressible fluids in a bounded domain. We find a unique solution to the initial-boundary value problem and show that it is near the analogous solution for an incompressible fluid provided the initial conditions

Reduction of Oxide Inclusions During the High‐Frequency Welding of Steel via a Nonthermal Ar/H2 Plasma Jet

open access: yesAdvanced Engineering Materials, EarlyView.
High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

ON WELL-POSEDNESS OF STEADY PROBLEM FOR MIXTURE OF COMPRESSIBLE VISCOUS FLUIDS FLOW AROUND AN OBSTACLE

open access: yesВестник Кемеровского государственного университета, 2014
The inhomogeneous boundary value problems for equations of mixture of compressible viscous fluids steady flow around an obstacle are considered. Existence and uniqueness of strong solution for such problem is proved.

Compressible flow computer program for gas film seals [PDF]

open access: yes, 1975
Computer program, AREAX, calculates properties of compressible fluid flow with friction and area change. Program carries out quasi-one-dimensional flow analysis which is valid for laminar and turbulent flows under both subsonic and choked flow conditions.

Effect of Oxygen Content on Surface and Subsurface Integrity During Turning of Ti–6Al–4V

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how oxygen content in the ambient atmosphere affects the surface and subsurface properties of Ti–6Al–4V during turning. Results show that oxygen does not influence surface roughness. However, machining in an extremely high vacuum‐adequate atmosphere increases surface hardness by up to 7.8% and induces compressive residual stresses ...

Flow field data of three-dimensional Riemann problems

open access: yesData in Brief
Common validation and verification test cases for compressible flow solvers are only one- or two-dimensional. Such flows, however, are inherently three-dimensional.
