摘要
According to this method: an internal liquid (Li) is made to flow through an internal flow member (2) and an external liquid (Le) is made to flow through an external flow member (4); conditions are firstly set up so that either droplets (G) of the internal liquid are formed in the external liquid, or a continuous jet of the internal liquid is formed in the external liquid; the flow rate of at least one of the two liquids is varied; a pair of transition liquid flow rate values are identified, from which either a continuous jet of the internal liquid is then formed in the external liquid or droplets of the internal liquid are then formed in the external liquid; and said value of the interfacial tension between these two liquids is deduced therefrom.
