Abstract:

An understanding of the physical properties of surfactant solutions is very important to confirm the mechanisms of boiling heat transfer enhancement by surfactant additives. In this paper，the experimental results of dynamic surface tensions，equilibrium surface tensions，viscosity，surface wettability，solubility and other physical properties of surfactant solutions based on boiling heat transfer enhancement by surfactant additives are presented and discussed to show the effects of surfactants on the physical properties of surfactant solutions. Then，some aspects of the physical properties of surfactant solutions which need to be investigated further are presented and some new ideas on the physical properties of surfactant solutions are given.
