|Abstract:||The ecological protection originated from marine engineering is the key factor for the healthy and sustainable development of marine ecological system. Combined with the tidal dynamic characteristics, a new optimistic ecological protection device concept model is designed for marine water intake engineering to avoid the ecological loss, which following the principles of safe, stable, easy installation and maintenance, unaffected water intake. Based on computational fluid dynamics (CFD), the three dimensional mathematical model of ecological protection device for marine water intake engineering is constructed to simulate and evaluate the feasibility of the proposed device. The flow field and pressure distribution are simulated and analyzed before and after the device installation. The numerical results of flow velocity in the intake, intake box and intake channel show that the ecological protection device has a weak effect on the flow field and the device can provide ecological safeguard for marine intake engineering. The pressure distribution from the ecological protection device would also reflect the underlying reason of the flow velocity change.|
