Abstract: Limitations in our understanding of the fluid dynamic phenomena encountered in fluidic elements and the resulting difficulty of the quantitative characterization for simple cataloging of the ...

Abstract: Lagally’s theorem is extended to a number m of moving and growing vortices arbitrarily situated behind a circular cylinder immersed in a time-dependent ambient flow. Lift, drag, and added-mass ...

Abstract: The lift, drag, and inertia coefficients and the first ten harmonics of the lift force have been determined through the use of four smooth, four sand-roughened, and one marine-roughened cylinders. ...

Abstract: The results of an experimental study of the forced and periodic breakdown of a confined vortex rotating in the opposite direction are presented. The vortex tube consists of two chambers connected ...

Abstract: The present study deals with torque and cavitation characteristics of idealized two-dimensional and axially symmetrical butterfly valves. Theoretical results obtained for the two-dimensional case ...

Abstract: The stability of fully developed Poiseuille flow pulsating under a harmonically and a nonharmonically varying pressure gradient was studied experimentally. The characteristics of turbulent plugs ...

Abstract: The in-line and transverse forces acting on circular cylinders placed near a plane boundary in a sinusoidally oscillating fluid in a U-shaped vertical water tunnel have been measured. The period ...

Abstract: A comprehensive review is presented of the computational methods based upon Helmholtz’s powerful concepts of vortex dynamics, making use of Lagrangian or mixed Lagrangian-Eulerian schemes, the ...
