System Experimental Research On Thermo-hydraulic Behaviors Of Heat Discharge Into Estuarine

Estuarine areas connected with land and sea often become transport hub and economic center, with the rapid economic development, increasing demand for electricity, power plants'are started to build., however, the construction of power plant would solve the problem about cooling water, and estuarine waters temperature thermal emission characteristics of the hydraulic system test of the sink is the basis for solving the above problems. Therefore experimental on thermo-hydraulic of heated discharge into estuarine waters and influencing factors of considerable academic and practical value.Physical model test is to analyze the cooling water in the receiving waters in an effective way to transport law of diffusion. In this paper, the table rows deep to take the project layout, by physical model tests, carried out a horizontal rectangular tank temperature and discharge into the waters of non-constant homogeneous thermal characteristics of the hydraulic system test tank research. The main contents include: 1. Look up a great deal of literature, understand the research methods of physical model simulation in cooling water engineering. Search the relative problems of physical model further.2. Analyze the simulation outline of thermo-hydraulic behaviors in physical model in estuarine water area ; by the model, planning and layout, machining and equipment installation and commissioning.3. The pilot cooling water is 800L/H,temperature rise is 10℃, carry out experiments on various flow 0L/s, 1L/s, 2L/s, 3L/s, 4L/s; depth of 10cm, 13cm, 16cm, 19cm; tidal range 2.7cm, 3.6cm, 4.5cm .The experiments include fifty three groups.4. Analysis impact of downstream water depth, upstream flow , tidal range of cooling water to the thermal characteristics of hydraulic . The results show that for non-constant homogeneous estuary waters under the same conditions of incoming flow and downstream water depth, with tidal increases, the area of temperature contour and intake temperature is reduced ; in the same tidal range and incoming flow with the increase of downstream water depth, temperature contour area increased, intake temperature is decreased; in the same conditions of tidal range and downstream water depth, with the increase of upstream flow, temperature rise contour area is reduced and the areas of temperature rise effected by downstream...
