This article represents experimental study work carried out on a single stage diffuser type centrifugal pump. The flow-induced pressure pulsations, mechanical vibrations and noise has been monitored during the experimentations for five different flow rates by varying the radial clearance. For each case of radial clearance and flow conditions, overall levels and frequency spectra, in a wide freq...

In the present study, an experimental investigation was performed to characterize the vortex induced vibration (VIV) of a flexible cable in an oncoming shear flow. The VIV tests were conducted in a wind tunnel with a flexible cable model. It was found that, under different oncoming velocity profiles, the cable model behaved in single-mode and multi-mode VIVs. The displacement amplitudes of the ...

For flow-induced vibration of a rounded-square cylinder under the effect proximity interference by stationary splitter plate downstream, numerical study is presented for various corner-radius R(0.1−0.5), reduced velocity U*(2−12.5), cylinder-plate gap G*(0.3,2.0), Reynolds number Re = 100, mass ratio M*=1, damping coefficient ζ=0.005, plate-length L*=1, and plate-thickness t*=0.05. R, vortex-in...

In this paper, the transverse vibration of a triple-walled carbon nanotube (TWCNT) conveying fluid flow is studied based on the strain/inertia gradient theory with van der Waals interaction taken into consideration. The nanotube is modelled using Euler-Bernoulli beam model and the Galerkin’s method is employed to obtain the CNT complex valued Eigen-frequencies. The effects of the fluid flow tho...
