Numerical Simulation And Analysis Of The High-level Water Collecting Cooling Tower

In the energy tense situation, the energy-saving technology level of the cooling tower is still relatively backward, the circulating water pump of the cooling system is oversized, and the phenomenon of the high energy consumption remains pervasive in the cooling tower, which results in improving the energy saving as an important and urgent task for the cooling tower. Therefore, it is important theoretical significance and engineering value to optimize the high income water cooling tower.The high-level water collecting cooling tower was studied in the paper. The actual size of the high-yield water cooling tower and the arrangement of the tower, a spray pipe, filler and water collection devices were selected. The reasonable geometric model was established by the software Gambit, and its grid was divided and the boundary conditions were set up. Based on the RNG k-? turbulence model, using the porous media model, the DPM model, and the SIMPLE algorithm, the outflow field of the high-income cooling tower was simulated and analyzed in three-dimension. The influence of the ambient wind speed on the flow distribution and the operating characteristics were obtained when the unit was running at rated working conditions.The structure parameter of the high yield water cooling tower was studied and analyzed by the numerical simulation software FLUENT in the paper. Comparing the outflow field and the operating characteristics of the high yield water cooling tower with the conventional cooling tower at ambient wind, the different characteristics of the performance was analyzed.The structural parameters of the high yield water cooling tower were designed and optimized in order to reducing the influence of the ambient wind on the inlet wind resistance in the peculiar collection devices. The different structural parameters flap layout program was raised, and which was comparatively analyzed and the optimal structural parameter was selected. The results shows that the effect of the received water is better than others when the flap angle and the plate length respectively are 45 ° and 0.2m as optimal structure size, and the ventilation resistance is lowest, and optimize the best results.
