Process of overburden failure in steeply inclined multi-seam mining: insights from physical modelling

open access: yesRoyal Society Open Science, 2021
Ground surface damage caused by steeply inclined coal seam mining is widely distributed in China, but there is little research on the failure process and movement mechanism of strata induced by steeply inclined multi-seam mining.

Droplet Asymmetric Bouncing on Inclined Superhydrophobic Surfaces [PDF]

open access: yesACS Omega, 2019
A droplet impacting on inclined surfaces yields more complex outcomes than on normal impact and the effect of the inclining angle on the impact dynamics is still in controversy. Here, we show that a drop impacting on inclined superhydrophobic surfaces exhibits an asymmetric rebound with a distinctive spreading and retraction along the lateral and ...

High-Reynolds shallow flow over an inclined sinusoidal bottom [PDF]

open access: yes, 2010
An experimental study of a turbulent free-surface shallow flow over an inclined sinusoidal bottom with a fixed corrugation amplitude is presented. A parametric analysis is performed by varying both the inclination angle and the Reynolds number.

Lie Group Analysis of Natural Convection Heat and Mass Transfer in an Inclined Surface

open access: yesNonlinear Analysis, 2006
Natural convection heat transfer fluid flow past an inclined semiinfinite surface in the presence of solute concentration is investigated by Lie group analysis. The governing partial differential equations are reduced to a system of ordinary differential

Thin Films Flow Driven on an Inclined Surface [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2012
The flow of unsteady incompressible two dimensional system flow of a thin liquid films with negligible inertia is investigated. Continuity equation and Navier-Stokes equations are used to obtain the equation that governs this type of flow.

Inclined Surface Locomotion Strategies for Spherical Tensegrity Robots

open access: yes, 2017
This paper presents a new teleoperated spherical tensegrity robot capable of performing locomotion on steep inclined surfaces. With a novel control scheme centered around the simultaneous actuation of multiple cables, the robot demonstrates robust ...

Non-contact ultrasonic detection of angled surface defects [PDF]

open access: yes, 2011
Non-destructive testing is an important technique, and improvements are constantly needed. Surface defects in metals are not necessarily confined to orientations normal to the sample surface; however, much of the previous work investigating the ...

Equilibrium of drops on inclined hydrophilic surfaces [PDF]

open access: yesPhysical Review E, 2001
Why does not gravity make drops slip down the inclined surfaces, e.g., plant leaves? The current explanation is based on the existence of surface inhomogeneities, which cause a sustaining force that pins the contact line. Following this theory, the drop remains in equilibrium until a critical value of the sustaining force is reached.

Study on evaluation for cutting performance of ball end milling with straight-line path method for inclined surface using 3D-CAD (Influence of feed direction on cutting mechanism)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
In this paper, the cutting mechanism and cutting performance of a ball end mill on an inclined surface using the straight-line path method are investigated. Ball end mills are used to make a variety of products such as molds and dies. However, due to the
