| Abstract |
Taiwan is located in an area with active plate motion. The Earthquake Tsunami heavily affect Taiwan. At present, coastal protection is mainly based on wave-absorbing facilities. However, offshore submerged breakwater structures are better for wave dissipation energy including maintenance coastal landscape and ecology systems. Isolation waves are used to simulate the tsunami generated by the earthquake. The approach is one of the options for coastal engineering. The test was carried out with four different heights and stepped on the surface, which are inserted into the open channel flow through test equipment. A high-speed camera was set up on the side of the waterway, and microscopic particles are scattered in the water to observe the particle motion and flow field changes when the separated wave passes through the submerged dike. Using the PIVLab software with PIV method to describe the vorticity and velocity fields generated by the movement of particles in water. The vorticity and velocity field generated by the stepped dike is greater than that of the smooth shape in the latent and stepped submerged embankments. Under continuous vorticity field image, it can be observed that the vortex will insert into the submerged dike shape and move, generating its vorticity and its waves. The energy dissipation effect, if the vorticity is getting greater then it means the wave energy dissipation better. |
