Asymmetric Tangential Velocity inside Switchbacks: Implication for Switchback Origin
The Astrophysical JournalSwitchbacks are structures in the solar wind marked by large rotations in the magnetic field direction without significant changes in its magnitude, typically accompanied by enhanced bulk speed.

The Tangential Velocity Estimation Algorithm for Space-borne SAR
Journal of Physics: Conference Series, 2021 Abstract This article presents a discussion of one of the important areas of application of synthetic aperture radars (SAR) – the moving target indication (MTI) mode. The principle of trajectory signal processing in MTI systems is based on the estimation of the Doppler frequency or phase shift of the echo signals due to the movement of ...

Velocity distribution and hydrodynamic drag in turbulent flow [PDF]
E3S Web of Conferences, 2023 This work aims to study the vertical velocity distribution in the near-wall layer of a pipe, channel, and boundary layer of a flat plate because these issues are of great practical and theoretical importance.

Hydrodynamic flow between rotating stretchable disks in an orthotropic porous medium [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 A mathematical model of convective steady flow over rotating disks in an orthotropic porous medium has been developed and solved the non-dimentional governing equations for flow by the shooting method that uses fourth order Runge- Kutta integration ...

Flow Field Simulation of Swirling Abrasive Jet Nozzle for Hard Rock Breaking
Geofluids, 2022 Radial jet drilling (RJD) technology has been proved to be an economical and efficient stimulation technology for oil and gas, geothermal, hydrate, etc. but conventional RJD technology adopts pure water jet to break rock and form laterals, which has low ...

The tangential velocity excess of the Milky Way satellites [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2017 Abstract We estimate the systemic orbital kinematics of the Milky Way classical satellites and compare them with predictions from the Λ cold dark matter (ΛCDM) model derived from a semi-analytical galaxy formation model applied to high-resolution cosmological N-body simulations.

Demonstrating Tangential Velocity by a Self-Coded Robot
Journal of Student Research, 2021 Tangential velocity is a concept that is often taught as a part of rotation, and is the linear velocity an object has as it turns about a fixed axis. The main goal of this research project was to examine this concept and demonstrate it on a self-coded robot.
