Experimental and Numerical Study on the Flow Field around Artificial Reef with Star Shape
نویسندگان
چکیده
The flow fields around single and two combinations of star shape artificial reefs are investigated both numerically and experimentally. The numerical model is based on the Reynolds Navier-Stokes (RANS) equations embedded with a RNG k-ε turbulence model and SIMPEC algorithm. The governing equations are solved by using finite volume method (FVM). Non-invasive particle image velocimetry flow field measurements was carried out to verify the numerical results with different arrangement plan of artificial reefs and inlet flow velocity. Overall, favorable agreement is found between the numerical results and laboratory measurements. The study results help to inform the scale and character of the major current arising from the star shape artificial reefs and examine how the distance between two artificial reefs affects the flow field.

Hydrodynamic Modelling of Coral Reefs:Ningaloo Reef-Western Australia
As with all coral reef systems, the ecology of Ningaloo Reef is closely linked to water circulation which transport and disperse key material such as nutrients and larvae. Circulation on coral reefs may be driven by a number of forcing mechanisms including waves, tides, wind, and buoyancy effects. Surface waves interacting with reefs have long been known to dominate the currents on many coral r...
متن کاملNumerical Investigation of Fluid Flow Characteristics Around Slide Gates Using Multi-Zonal Method
One method of solving the governing equations of fluid flow about complex geometries is to use multi-zonal method. In this method the overall domain is divided into small number of simpler domains. In each zone, the flow field is solved independently of other zones. The boundary conditions for connecting zones are enforced to convey the necessary linkage. This multi – zonal procedure has been a...

متن کاملNumerical simulation of effect of non-spherical particle shape and bed size on hydrodynamics of packed beds
Fluid flow has a fundamental role in the performance of packed bed reactors. Some related issues, such as pressure drop, are strongly affected by porosity, so non-spherical particles are used in industry for enhancement or creation of the desired porosity. In this study, the effects of particle shape, size, and porosity of the bed on the hydrodynamics of packed beds are investigated with three ...
متن کامل3D Numerical Study on Scouring Around Bridge Piers Under Unsteady Flow Condition
Local scouring around the bridges piers has always been considered as a problem, especially in rivers. If we do not take the necessary actions to avoid the occurrence of this phenomenon or to reduce its influence, then the bridge's piers will be destroyed. Placing the bridge piers' foundation far from the earth's surface will turn out in a plan which is not economic at all. Experimental studies...
