Estimation of the radial distribution of the tangential velocity in a vortex chamber
Journal of Thermal Science, 2009The estimation of maximum tangential velocity becomes a very important factor for the estimation of performances of the vortex chamber. In this paper, a proposed flow model of how to estimate the maximum tangential velocity in the special form of the vortex chamber is described in detail.

The three-dimensional distributions of tangential velocity and total-temperature in vortex tubes
Journal of Fluid Mechanics, 1971 The axial and radial gradients of the tangential velocity distribution are calculated from prescribed secondary flow functions on the basis of a zero-order approximation to the momentum equations developed by Lewellen. It is shown that secondary flow functions may be devised which meet pertinent physical requirements and which at the same time lead to ...

Physics Letters, Section A: General, Atomic and Solid State Physics, 2022 It is well known as the Kelvin-Helmholtz instability (KHI) that an interface of tangential velocity discontinuity is necessarily unstable, regardless of the velocity difference's strength.

Accurate tangential velocities for solid fluid coupling
Proceedings of the 2009 ACM SIGGRAPH/Eurographics Symposium on Computer Animation, 2009We propose a novel method for obtaining more accurate tangential velocities for solid fluid coupling. Our method works for both rigid and deformable objects as well as both volumetric objects and thin shells. The fluid can be either one phase such as smoke or two phase such as water with a free surface.

A Complementarity Formulation of the Tangential Velocity Slip Problem in Lubricant Films
, 2013 This contribution deals with a modelling of the tangential velocity slip problem in terms of variational inequalities. In particular, the critical shear stress criterion is considered. The theoretical conditions under which a unique solution exists are discussed and an algebraic description based upon a complementarity approach is presented, similar to

Robot trajectory planning by assigning positions and tangential velocities
Robotics and Computer-Integrated Manufacturing, 2013A technique for the robot trajectory planning is proposed.The technique mainly consists in controlling a manipulator by assigning not only the way points on the path but also the geometrical tangent of the desired path shape at each of those points.This is achieved by assigning to the control system not only the joint variables { q i } , but also the ...

Tangential velocity effects in gas-surface scattering
Chemical Physics Letters, 1974Abstract An analytical surface model that alters the tangential velocity component by a periodic, time-dependent force and reflects the normal velocity component specularly is presented. Single and double lobe distributions with and without reverse scattering are obtained.

Effect of particle tangential velocity on erosion ripple formation
Wear, 1995Abstract The formation of ripples on the surface of pure aluminum during solid particle erosion was studied using sharp alumina and spherical glass beads as erodent particles in an air-blast type system. A new laboratory technique controlled the tangential velocity of the erodent particles relative to the samples with their placement on a velocity ...

Radiation of Hydromagnetic Waves from a Tangential Velocity Discontinuity
The Physics of Fluids, 1971An outgoing group velocity criterion is used to determine the regions of existence of radiation modes for a tangential velocity discontinuity in a collisionless hydromagnetic régime. It is shown how previously published results must be corrected.

On tangential velocity discontinuities being coincident with stress discontinuities
International Journal of Mechanical Sciences, 1982Abstract Whether or not in a slip-line field a stress discontinuity can be simultaneously a velocity discontinuity has been discussed since the late 1940s. According to the usual “jump” conditions it is not impossible to have a tangential velocity component across a stress discontinuity.
