Résumé

Phase change emulsion (PCE) is a kind of novel heat transfer fluid with greater apparent specific heat and stronger heat transfer capacity than water. The laminar rheological characteristics of a type of PCE developed by the authors were experimentally studied. And the advantage of applying this kind of PCE as a heat transportation fluid was discussed. The results show that: (a) its viscosity is about 5.57 times of that of water, which is much lower than those reported in the literature; (b) it can be considered as Newtonian fluid from its rheological characteristics and its friction factor conforms to the rule of 64/Re; and (c) for given heat transportation quantity, due to which greater apparent specific heat, the mass flow rate and the pump consumption for the PCE decrease greatly compared with water.
