Method for selecting test fishes in fish passing facility model
According to the method for selecting the test fishes in the fish passing facility model, juvenile fishes of the same type are selected according to fish passing objects and used for describing the swimming ability of the fishes, k is a dimensionless variable, L is the body length of the fishes and the unit m, and dimensional harmony of a water flow velocity index and a fish swimming ability index in a reduced scale model is guaranteed. Calculating according to the average body length of the target fish by taking the length scale lambda1 as a conversion standard to obtain a body length numerical value of the test fish; and calculating the body length of the fish for the test by taking a flow velocity scale lambda v as a conversion standard according to a principle that the critical flow velocity of the target fish is matched with the maximum flow velocity of the model, so as to obtain a body length numerical value of another fish for the test. And comparing the body length values of the test fish calculated according to the length scale and the flow velocity scale, and selecting the larger body length as the final body length of the test fish. According to the method, the selection problem of test fishes in a fish passing facility model is well solved.
本发明提供一种过鱼设施模型中试验用鱼的选择方法，根据过鱼对象选择同种类的幼鱼，使用来描述鱼类的游动能力，其中k是一个无量纲变量，L是鱼的体长，单位m，保证了缩尺模型中水流流速指标与鱼类游泳能力指标的量纲和谐。以长度比尺λl为换算标准，根据目标鱼类的平均体长进行计算，获得一个试验用鱼的体长数值；以流速比尺λv为换算标准，根据目标鱼类的临界流速和模型最大流速相匹配的原则，进行试验用鱼体长的计算，获得另一个试验用鱼的体长数值。将分别按照长度比尺和流速比尺计算所得的试验用鱼体长数值进行比较，选择较大者作为最终试验用鱼的体长。本发明很好的解决了过鱼设施模型中试验用鱼的选择问题。
