Forced axial segregation in axially inhomogeneous rotating systems

Physical Review E, 2015
Controlling segregation is both a practical and a theoretical challenge. Using a novel drum design comprising concave and convex geometry, we explore, through the application of both discrete particle simulations and positron emission particle tracking, a means by which radial size segregation may be used to drive axial segregation, resulting in an ...

Optimization design for reducing the axial force of a vaned mixed-flow pump

Engineering Applications of Computational Fluid Mechanics, 2020
Vaned mixed-flow pump is widely used for liquid transportation in industry and agriculture. The structural-asymmetricity induces large axial force which causes axial vibration and shaft system damage.

Skyrme-force time-dependent Hartree-Fock calculations with axial symmetry [PDF]

, 1981
We discuss axially symmetric time-dependent Hartree-Fock calculations using a finite-range modification of the Skyrme energy functional. The finite-difference forms of the coordinate-space time-dependent Hartree-Fock equations, the method of time ...

Tension Force Estimation in Axially Loaded Members using Wearable Piezoelectric Interface Technique

Sensors, 2018
Force changes in axially loaded members can be monitored by quantifying variations in impedance signatures. However, statistical damage metrics, which are not physically related to the axial load, often lead to difficulties in accurately estimating the ...

Bolt axial force measurement using Digital Image Correlation Method considering bending force on bolt

Nihon Kikai Gakkai ronbunshu
As a simple and highly accurate axial force management method during manufacturing and maintenance of bolt-tightened structures, we examined a method to calculate the axial force from images of the bolt head. In this method, the axial force is calculated
