Broadband Multizone Sound Rendering by Jointly Optimizing the Sound Pressure and Particle Velocity

open access: yes, 2017
In this paper, a recently proposed approach to multizone sound field synthesis, referred to as Joint Pressure and Velocity Matching (JPVM), is investigated analytically using a spherical harmonics representation of the sound field.

Multi-objective optimization of a threading machine for tobacco leaves

open access: yesEngineering and Applied Science Research, 2022
The threading of Turkish or Oriental tobacco leaves is part of the sun drying process prior to cigarette production. In Thailand, tobacco leaves tend to be threaded manually by farmers, resulting in low production capacity due to insufficient labor being

Component Velocities and Turbulence Intensities within Ship Twin-Propeller Jet Using CFD and ADV

open access: yesJournal of Marine Science and Engineering, 2020
This study presents the decays of three components of velocity for a ship twin-propeller jet associated with turbulence intensities using the Acoustic Doppler Velocimetry (ADV) measurement and computational fluid dynamics (CFD) methods. Previous research

A universal velocity distribution of relaxed collisionless structures

open access: yes, 2005
Several general trends have been identified for equilibrated, self-gravitating collisionless systems, such as density or anisotropy profiles. These are integrated quantities which naturally depend on the underlying velocity distribution function (VDF) of

Slowly rotating Bose Einstein condensate galactic dark matter halos, and their rotation curves

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
If dark matter is composed of massive bosons, a Bose–Einstein condensation process must have occurred during the cosmological evolution. Therefore galactic dark matter may be in a form of a condensate, characterized by a strong self-interaction.

A model for collisions in granular gases

open access: yes, 1996
We propose a model for collisions between particles of a granular material and calculate the restitution coefficients for the normal and tangential motion as functions of the impact velocity from considerations of dissipative viscoelastic collisions ...

Pulsed plasma accelerator operates repetitively without complex controls [PDF]

open access: yes, 1965
Self-repeating pulsed plasma accelerator operates with a wide variety of gases over a large range of pressures without complex control equipment. The accelerator combines a circular channel with a tangential channel at the entrance way of a high-velocity

Impact of Spin Slip Conditions on the Axisymmetric Rotation of a Spherical Particle in a Couple Stress Fluid Within a Cavity

open access: yesEngineering Transactions
This paper investigates the effect of spin slip condition on the flow of a couple stress fluid between two concentric spheres. The spherical particles rotate about the z-axis with different angular velocities  and  under the assumption of low Reynolds ...
