Abstract

The invention discloses a medium-shallow water homodromous wave current generating method and an experimental water channel. The generating method and the experimental water channel are characterized in that flow distribution channels which are symmetrically bent to the water channel are formed in the two ends of a reservoir, one end of the water channel is fixed on the ground through a triangular fixing support, the other end of the water channel is supported by a lifter, changes of the slope of the water channel can be achieved through adjustment of the lifting height of the lifter, the front end of the water channel is provided with a wave generation plate connected with a wave generation machine, the tail end of the water channel is provided with a side flow channel, a wave-eliminating fixed slope, an arc lifting plate and a wave eliminating device, the tail end of the side flow channel of the water channel is connected with a down pipe and then connected to a water storage tank through a collecting pipe, the water storage tank is connected with a water supply pipe, the tail end of the water supply pipe perpendicularly stretches into the reservoir, and water supply for the reservoir is achieved with the action of a water pump. According to the manufacturing method and the experimental water channel, independent wave current generating can be achieved, homodromous wave current generating also can be achieved, and the experimental research and teaching requirement for load response of a structural object under the action of wave currents at the same time can be met.

Description

technical field [0001] The invention relates to the field of port, coast and offshore engineering test research, in particular to a method for manufacturing co-directional wave flow in medium and shallow water and an experimental water tank. Background technique [0002] The 21st century is the century of the ocean. With the rapid development of society, the demand for energy in various countries is increasing day by day. It has become an inevitable trend to vigorously exploit and develop offshore oil and gas. The oil and gas resources in the sea area under our jurisdiction are very rich, especially in the South my country Sea, which is known as the second "Persian Gulf". In recent years, in order to vigorously develop marine resources, many oil production platforms and drilling platforms have been built in offshore waters and a large number of submarine oil pipelines have been laid. Nearshore waves are one of the most important dynamic factors in the nearshore marine envir...
