نویسندگان
چکیده
In the present study, turbulent flow visualization is carried out to understand the vortex formation mechanism behind a trapezoidal bluff body, for vortex flowmeter application. The dye used for flow v isualization is shearthickening and h igh extension viscosity fluid, which can sustain turbulent separated flows. W ith the quantitative assessment of the images, the vortex frequency is computed which is in close match with the results obtained from Piezo-electric sensor based measurement. The study enhances the understanding of the complex vortex format ion mechanis m in the design of vortex flowmeter.

متن کاملAcceleration of Bluff Body Calculation Using Mdgrape-2
Bluff body calculation was accelerated by using a special-purpose computer, MDGRAPE-2, that was exclusively designed for molecular dynamics simulations. The three main issues were solved regarding the implementation of the MDGRAPE-2 on vortex methods. These issues were the efficient calculation of the Biot-Savart and stretching equation, the optimization of the table domain, and the round-off e...
متن کاملNumerical Simulation of the Incompressible Laminar Flow Over a Square Cylinder
Simulation of fluid flow over a square cylinder can be performed in order to understand the physics of the flow over bluff bodies. In the current study, incompressible laminar flow over a confined square cylinder, with variable blockage factor has been simulated numerically, using computational fluid dynamics (CFD). The focus has been on vortex-induced vibration (VIV) of the cylinder. Vorticity...
متن کاملEffects Of Frequency Variation At Inlet Flow On The Vortex Shedding Frequency Behind A Circular Cylinder
In many applications the flow that past bluff bodies has frequency nature (oscillated) and it is not uniform. This kind of flow has effects on the formation of vortex shedding behind bluff bodies. In this paper the flow around a circular cylinder was numerically simulated. The effects of frequency variation at inlet flow on the vortex shedding frequency were investigated. The transient Two-Dime...
