Description

technical field [0001] The invention relates to the field of hydraulic model tests of offshore engineering, in particular to a model test device and method for a shore-type oscillating water column wave energy conversion device. Background technique [0002] In nature, the ocean area accounts for about 71% of the total area of ​​the earth, which contains a huge wave energy reserve. The global exploitable annual wave energy reserve can reach 2TW, and wave power can be generated 90% of the time in a year. Wave energy is a high-quality renewable energy, and its scientific development is of great significance to alleviating the energy crisis and solving environmental pollution problems. [0003] In order to develop and utilize wave energy, many marine countries have actively carried out research on the development and utilization of wave energy, and have made great progress, and have explored and designed various types of wave energy conversion and utilization devices. The exis...

Problems solved by technology

[0004] Among the published patent schemes, the technical schemes focusing on the model test design of the oscillating water column wave energy conversion device are relatively lacking; most of the model tests of the oscillating water column wave energy conversion device that have been carried out have many device model components and complex structures. It is necessary to remake the model in each test process, which leads to high test cost and other problems; at the same time, in the existing model test design, there is little consideration to explore the influence relationship between the geometric shape change of the device model and the coupling effect of damping change on the overall wave energy conversion rate of the device.
