ABSTRACT:
Heat exchange fluids are improved by incorporating therein a viscoelastic surfactant composition. The viscoelastic surfactant is employed in an amount sufficient to reduce the friction experienced by the heat transfer fluid in a heat transfer apparatus while providing good heat transfer. The improved fluids are useful in district heating applications.
