To explain the decrease of the characteristic frequency of the flow fluctuations due to the fences, an analytical model is developed, based on vortex dynamics.
A two-dimensional potential flow model based on the vortex blob method, used to simulate the flow in the junction, describes accurately the flow visualization and laser Doppler data obtained in pipes with square cross-sections and with sharp edged junctions.
The annular centrifugal contactors based on the Taylor-vortex flow have a great potential in chemical, nuclear, metallurgy and biotechnology industry.
The flow structure alteration around the bluff bodies and the shear layer shift phenomenon observed on the trailing edges were then investigated for interpreting the control mechanism for this flow-induced noise suppression, which were based on the vortex shedding strength suppression and vortex shedding frequency shift phenomenon.
The process intensification analysis based on flow patterns from a CFD (computational fluid dynamics) simulation indicated that the vortex flow presented multi-dimensional velocities including a V-shaped tangential velocity profile and non-uniform axial velocity profile, which resulted in enhancement of gas liquid contact, mixing, mass transfer, and reaction compared to non-vortex flow.
Wang et al. [7] experimentally studied the fatigue damage caused by vortex-induced vibration based on rain-flow counting and a standard S N curve in an ocean basin.
A new method in which mass flow rate can be directly measured based on the vortex shedding principle is presented in this paper.
Two ways of building airfoil database and current progress of the approach based on Momentum, Vortex and Cascade are addressed.
A mathematical model for vortex-induced vibration of circular, cylindrical structures that is presented in this paper is based on the unsteady flow theory.
Based on the potential flow theories, the effects of terrains on the wind field are considered by a serial of two-dimensional vortexes, whose strengths are solved by combining with the ground boundary conditions.
