【摘要】 本文采用L_∞稳定的分步杂交方法,数值模拟了热电厂冷却水系统在潮汐作用下的取水温度和水环境温度,对其水力热力特性和水环境污染进行了预测。计算的潮位、流速与原体实测资料吻合良好,平均取水温升和远区环境水温与物理模型试验也很一致。更多还原

【Abstract】 In this paper a numerical simulation for intake water temperature and aquatic environment temperature field of cooling water system for the thermal power plant under the action of tide motion by using the hybrid method of fractional steps with L∞-stability is given, and its hydro-thermal behavior and environment pollution are predicted. The computed elevation of water and velocity field are in good agreement with the prototype observations, and the average intake water temperature and aquatic environment temperature distribution are also in consistent very well with the laboratory experiments.更多还原
