摘要： On the basis of computational fluid dynamics, the flow field characteristics of multi-trophic artificial reefs, including the flow field distribution features of a single reef under three different velocities and the effect of spacing between reefs on flow scale and the flow state, were analyzed. Results indicate upwelling, slow flow, and eddy around a single reef. Maximum velocity, height, and volume of upwelling in front of a single reef were positively correlated with inflow velocity. The length and volume of slow flow increased with the increase in inflow velocity. Eddies were present both inside and backward, and vorticity was positively correlated with inflow velocity. Space between reefs had a minor influence on the maximum velocity and height of upwelling. With the increase in space from 0.5 L to 1.5 L (L is the reef lehgth), the length of slow flow in the front and back of the combined reefs increased slightly. When the space was 2.0 L, the length of the slow flow decreased. In four different spaces, eddies were present inside and at the back of each reef. The maximum vorticity was negatively correlated with space from 0.5 L to 1.5 L, but under 2.0 L space, the maximum vorticity was close to the vorticity of a single reef under the same inflow velocity.
