開水路流れにおける輸送過程

Abstract

This paper concerns with the mass transfer processes of dissolved materials inserted as aninstantaneous line source in the open-channel flow reviewing the lateral diffusion in concentra-tion. Experimental studies made in a rectangular laboratory flume consist of two series.Data obtained were treated by the statistical analysis like the lateral distribution of con-centration, first moment, second moment, peak concentration, and so on, with results of newknowledges in the statistical characteristics of mass transfer and in the practical application ofone-dimensional mass transfer analysis in open-channel flows.
