The tangential velocity in the hydrocyclone [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета, 2020
Based on the Navier-Stokes equation, the paper presents the derivation of the tangential flow velocity formula in a hydrocyclone. The derivation coincides with the solution of the vorte3x filament diffusion problem.

Uncertainty in the numerical prediction of the tangential velocity in axial turbines at part load operations: A parametric study

open access: yesEnergy Reports, 2023
Numerical simulations of axial hydraulic turbines away from the best efficiency point are challenging. Previous studies especially show difficulties predicting the tangential velocity at Part Load (PL) operating conditions, where the swirl is high, in ...

Velocity coefficient of tangential supply of subsonic centripetal turbine [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение", 2022
Today, in the spectrum of tasks solved by orbital spacecraft, there is a direction associated with an increase in both functional and thermal power radiated by the thermal control system into outer space.

Evolution of plane curves with a curvature adjusted tangential velocity [PDF]

open access: yesJapan Journal of Industrial and Applied Mathematics, 2011
We study evolution of a closed embedded plane curve with the normal velocity depending on the curvature, the orientation and the position of the curve. We propose a new method of tangential redistribution of points by curvature adjusted control in the tangential motion of evolving curves.

Velocity distribution and hydrodynamic drag in turbulent flow [PDF]

open access: yesE3S 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]

open access: yesSongklanakarin 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 ...

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.

Experimental evaluation of tangential contact force characteristics between wheel and rail focusing on water flow rate

open access: yesNihon Kikai Gakkai ronbunshu, 2022
This paper describes the relationship between a tangential contact force and a slip ratio under various wet condition. In previous studies, the effect of difference in watering amount on the tangential contact force characteristics under wheel/rail ...
