基于人工光源加热的水库水温结构模拟技术探索
An explorative study on simulation of reservoir water temperature structure based on artificial light heating
摘要
Abstract
According to the principle of spectrum consistence,dysprosium lamp is taken as the energy source to simulate the solar radiation for the explorative study made on the simulation of reservoir water temperature structure.A certain vertical water temperature structure can be formed through lighting the water surface with the solar radiation simulated by the dysprosium lamp.It is found out from the observation made on the heating effect of the dysprosium lamp on the under-surface water body that the strength of the light source which is several times of that of the natural solar radiation can make an obvious temperature rise of the water body with an area about 20 cm under the water surface within only several hours,but the heating effect is very limited on the deeper water body.Therefore,the experimental model for the reservoir water temperature stratified structure under the water surface heat exchange can be designed in accordance with the horizontal distorted scale under the consideration of the property of the dysprosium lamp that can heat the surface water body rapidly.Moreover,based on the concept of comprehensive parameters,the solar net radiation flux coefficient Φ and the surface heat transfer comprehensive coefficient K are introduced,and then the similarities are preliminarily deduced as well.Under the condition of same basic water temperatures,the solar net radiation flux coefficient and the surface heat transfer comprehensive coefficient of both the prototype and the model are to be theproportional relationship of λΦ =λK =λt1/2.关键词
