Abstract: abstract:Artificial reefs fulfill a similar role to that of coral reefs in providing a suitable living environment for fish and a vast array of other marine life and microorgansisms. Recent studies have demonstrated the value of investigating the flow phenomena in and around artificial reefs as a means of identifying their fish-attracting features. Field measurements of the flow field have traditionally been obtained using some form of probe mounted on the reef itself. However, such instrumentation tends to disturb the flow, and hence the acquired data may not accurately reflect the true features of the flow field. Accordingly, this study conducts non-invasive particle image velocimetry (PIV) measurements to study the flow patterns in and around an artifical reef deployed within a horizontal circulating water channel. The PIV results are then used to verify the numerical results obtained from finite volume method (FVM) simulations of the same flow scenario. The good general agreement found between the two sets of results indicates that numerical methods provide a valid and powerful means of modeling the flow fields in and around artificial reefs. Particularly, numerical simulation techniques offer the potential to explore the complex flow phenomena induced by double and multiple-reef block configurations, and therefore overcome the size constraint limitations of conventional PIV-based experimental methods.
