Effects of Tangential Velocity in the Reactive Relativistic Riemann Problem [PDF]

open access: yesThe Astrophysical Journal, 2019
Abstract Type I X-ray bursts are thermonuclear burning events that occur on the surfaces of accreting neutron stars. Burning begins in a localized spot in the star’s ocean layer before propagating across the entire surface as a deflagration. On the scale of the entire star, the burning front can be thought of as discontinuity.

Theoretical Model of Tangential Contact Stiffness and Damping of Solid-Liquid Interface in Macroscopic Relative Motion

open access: yesIEEE Access, 2023
The macroscopic relative motion solid-liquid interface widely exists in the contact motion pairs of machine tools and other mechanical equipment. In order to accurately obtain the tangential contact stiffness and damping parameters, the Savkoor asperity ...

Experimental investigation on free surface vortices driven by tangential inlets [PDF]

open access: yes, 2016
Particle Image Velocimetry (PIV) measurements have been carried out in order to analyze the structure of free surface vortices in a promoting geometry with two tangential inlets. Velocity fields associated to the free surface vortex have been obtained at

MEAN-LINE FLOW MODEL OF VISCOUS LIQUIDS IN A VORTEX PUMP

open access: yesTASK Quarterly, 2023
The axial, radial and tangential velocity profiles of six fluids were extracted from computational fluid dynamics simulation results at points in a pump chamber 1 mm distant from the blades in a vortex pump at the specific speed of 76.

Perceptual judgments of duration of parabolic motions

open access: yesScientific Reports, 2021
In a 2-alternative forced-choice protocol, observers judged the duration of ball motions shown on an immersive virtual-reality display as approaching in the sagittal plane along parabolic trajectories compatible with Earth gravity effects.

Galactic rotation curves in modified gravity with non-minimal coupling between matter and geometry [PDF]

open access: yes, 2010
We investigate the possibility that the behavior of the rotational velocities of test particles gravitating around galaxies can be explained in the framework of modified gravity models with non-minimal matter-geometry coupling. Generally, the dynamics of

R fluids [PDF]

open access: yes, 2007
A theory of collisionless fluids is developed in a unified picture, where nonrotating figures with anisotropic random velocity component distributions and rotating figures with isotropic random velocity component distributions, make adjoints ...

Characteristics of Air Flow and Heat Transfer in Serpentine Condenser Pipes with Attached Convection Plates in Open Channel

open access: yesInternational Journal of Technology, 2020
Many efforts have been made to reduce the energy consumption of household refrigerators. One method is to place the pipe condenser to increase the rate of heat release.

THE ROLE OF TANGENTIAL VELOCITY IN EXPLOSIVE INITIATION BY FRAGMENT IMPACT

open access: yesProceedings of the 32nd International Symposium on Ballistics, 2022
An initiation study is presented in which we examine the effect of the normal and the tangential velocity components of a fragment that impacts a covered and a bare Comp-B explosive. The study is based on calibrated numerical Lagrangian simulations using the LS-Dyna hydrocode.
