Embodiment 1
[0094] Example 1, see figure 1 , 2 , 3, 4, first step, according to the set of numerical sink sizes and the position of the arc type Broken buffet structure, the consolidation of the calculation area is generated by the Cartesian coordinate system; uniformly divided into the grid in the horizontal and vertical direction of the water tank. The total length of the grid is greater than the sum of water depth and maximum wave, and there is a certain amount of empty grid to ensure that the fluctuate surface is not limited by the upper boundary;
[0095] Step 2, initialize the numerical parameters of the calculation area, the speed at all grid points in the calculation area is set to zero, and the pressure on the whole country is set according to the static water pressure distribution.
[0096] In the third step, based on Renault-based NS equation simulation considering fluid viscous wave movement, a turbulent model is closed, and the NS equation group is closed as a calculation method...

The invention provides a stress calculating method for an arc-plate type breakwater based on a virtual boundary force method. The method comprises the following steps: simulating to consider viscous wave motion based on a reynolds-average N-S equation set; using a turbulence model closed N-S equation set as a control equation of the calculating method disclosed by the invention; simulating interaction between waves and the arc-plate type breakwater by using the virtual boundary force method. Compared with a traditional stress calculating method for the arc-plate type breakwater, the stress calculating method provided by the invention has the advantages that the interaction between the waves and the arc-plate type breakwater is described by using the virtual boundary force method and arrangement of boundary conditions on the surface of the arc-plate type breakwater are not needed, so that the numerical calculation efficiency can be greatly improved.
Description
Technical field: [0001] The present invention relates to the field of Bangobu Engineering, in particular, a method of calculating the force-arc plate type bobbin based on the virtual boundary force; the invention can be used in the large marine platform, semi-circular breeze and other marine engineering irregular structural research. Background technique: [0002] As a new type of parallel structure, the arc plate type Broken buffet can be formed by an anchor chain into a floating blast, and can also be supported by a pile foundation. Compared to traditional hiking anti-wave structures, the arc plate-type non-wave embankment has many advantages, which can effectively dissipate wave energy by destroying the waterpit slide, while combining the foundation requirements, simple structure, convenient construction, ecological environmental protection, saving Materials and benefits for free exchange of water in front of port areas, in line with the basic requirements of the "Green Ecolog...
