FAQs - Shear7

The Strouhal number depends on a number of factors including the direction of vibration (in-line vs cross flow VIV), whether the cylinder is fixed or freely vibrating and the Reynolds number. SHEAR7 is validated against experiments ranging between 0.15 to 0.25 however. A relevant paper on Strouhal numbers is OMAE2018-51241.

Vibration Stone Screening Machine For Separating Stone

SIEBTECHNIK linear-motion screening machines are freely vibrating machines, that is, the vibration amplitude freely adjusts itself to suit the mass ratio of screen box and unbalance mass. Linear-motion screening machines are designed with a selectable steep (approx. 75 ) or shallow (approx. 40 ) throw angle and are therefore flexible with.

Dec 18, 2021In this paper, we present a deep learning-based reduced-order model (DL-ROM) for the stability prediction of unsteady 3D fluid-structure interaction systems. The proposed DL-ROM has the format of a nonlinear state-space model and employs a recurrent neural network with long short-term memory (LSTM). We consider a canonical fluid-structure system of an elastically-mounted sphere coupled with ...

A detailed analysis of the distribution of the eigenvalues of the transfer (or, system) matrix of the reduced VIV system shows that the frequency range of the lock-in can be partitioned into resonance and flutter lock-in regimes. The resonance lock-in (lower branch of the VIV response) dominates the fluid-structure interaction.
