水流的紊动混合 由于水流紊动而引起的水体中动量、热量和质量的混合现象。在静止水体中或作层流运动的水流中,悬浮微粒不停地进行布朗运动,产生物质迁移现象。例如,向静止水体投入有色溶液,便会由于布朗运动,而使溶液向整个水域扩散,这种现象称为分子扩散。在紊流中存在着大小不等的涡漩,这些涡漩也在相互交错不停地运动着,这种运动现象称为紊动。紊动与布朗运动类似,使水中的动量、热量与质量向全部水域扩散,称为紊动扩散。紊动扩散最终将导致水中动量、热量与质量的充分混合。 美国人A.斐克于1855年首先提出液体中分子扩散定律,指出在各向同性的水体中,单位时间通过单位面积的质量与该断面的浓度梯度成比例。英国人G.I.泰勒通过实验和理论分析,于1921年提出,紊动扩散机制与分子扩散机制是相似的,因而也可应用斐克定律来分析紊动扩散现象,从而为研究紊动扩散奠定了理论基础。此后,美国人V.A.范诺尼、H.劳斯、D.W.普里查德和英国人K.F.鲍登应用紊动扩散理论研究细粒泥沙在水中的运动和河口淡水同盐水的混合。20世纪60年代后期,随着环境科学的发展,美国G.T.乔那迪和H.B.费希尔等人研究了污染物质在水中的紊动扩散,提出了紊动扩散及分散方程的各种实用形式,使紊动混合的研究不断完善。 根据质量平衡方程和斐克定律,可以推导出紊动水流中悬浮物质的对流扩散方程,在恒定均匀流情况下,三维对流扩散方程为
