TL;DR: A review of simplified seismic design procedures for elevated tanks and the applicability of general-purpose structural analyses programs to fluid-structure-soil interaction problems for these kinds of tanks is presented in this paper.

TL;DR: In this article, a mathematical model is proposed to describe the phenomena of parallel-flow-induced vibrations of a flexible rod, and a solution is obtained for a rod with arbitrary end conditions; the solution can be used for fixed, hinged, cantilevered and other elastically supported end conditions.

TL;DR: In this paper, a finite difference method is employed to solve the incompressible Navier-Stokes equations in the primitive-variables formulation, and test cases were used to guide selection of the size of flow domain, numerical parameters, and to verify that the resultant method was both convergent and accurate.

TL;DR: In this paper, the authors discussed and tested theories of particle removal by high-frequency ultrasonic waves against recent experimental data and showed that highfrequency ultrasound can clean particles most effectively in media with properties like water because: (1) the wavelength can be made comparable to the particle radius to promote effective sound-particle interaction; (2) the viscous boundary layer is thin, minimizing particle hideout; and (3) both the added mass and radiation pressure forces exceed typical adhesion forces at high frequencies.
Abstract: In this paper, theories of particle removal by high-frequency ultrasonic waves are discussed and tested against recent experimental data. First, the principal adhesion forces such as van der Waals forces are briefly reviewed and the typical uncertainties in their size in particle-surface systems are assessed. The different ultrasound-induced forces-linear forces such as added mass, drag, lift, and Basset forces and nonlinear ones due to radiation pressure, and drag exerted by acoustic streaming-are discussed and their magnitudes are evaluated for typical cleaning operations. It is shown that high-frequency ultrasound can clean particles most effectively in media with properties like water because: (1) the wavelength can be made comparable to the particle radius to promote effective sound-particle interaction; (2) the viscous boundary layer is thin, minimizing particle "hide-out;" and (3) both the added mass and radiation pressure forces exceed typical adhesion forces at high frequencies. Based on these analyses, possible mechanisms of particle removal are discussed and interpreted in terms of experimental observations of particle cleaning. >
