在给水处理工作中,沉淀池模型试验一般应用于三个方面:1.研究水流和泥沙运动的规律;2.检核原设计能力或生产构筑物效果,为设计或改造提供数据和条件;3.研究新型构筑物的水力性能。在为第二方面的目的而进行试验时,必须回答人们经常提出的问题,即如何考虑模型?模型是否能复演原形条件?模型中测定值如何返回原型等。为了科学地回答这一系列回题,前人对模似律做了大量的研究工作,但未能完善地
In the water treatment work, the sedimentation tank model test is generally applied in three aspects: 1. Study the laws of water flow and sediment movement; 2. Check the original design ability or effect of the production structure, provide data and conditions for the design or transformation; 3 Study the hydraulic performance of new structures. When conducting experiments for the purposes of the second aspect, it is necessary to answer questions that people often ask, namely, how to consider the model, whether the model can reproduce the prototype conditions, how to return the measured values in the model, and so on. In order to answer this series of questions scientifically, the predecessors have done a lot of research on model law, but they have failed to improve
