The Enhancement of Marangoni Condensation Heat Transfer by Addition of Additives Available to Purchase

This paper investigated the heat transfer process that the condensing occurred on the tube and the vapor has been added with effective additives. The effective additives trigger interfacial convection that leads to loss of hydrodynamic stability at the liquid/vapor interface and produce a spontaneous disturbance in the condensate liquid. As a result, condensation heat transfer is significantly increased. Both physical models included the condensate liquid film and mathematical model based on the boundary layer equation were given and then transformed to a non-dimensional form by applying the similarity theory. The main concept of developing the model is to understand the basic mechanism of surface tension effect on the process of steam condensation.
