Abstract:
1. A fluid composition, comprising: a coolant comprising a liquid alcohol freezing point depressant comprising a glycol; and a corrosion inhibitor selected from the group consisting of organic acid corrosion inhibiting agents, silicate corrosion inhibiting agents, and combinations thereof; said corrosion inhibitor being present in an amount sufficient to provide corrosion inhibition to metal surfaces in contact with the coolant; and nanoparticles dispersed throughout the coolant, the nanoparticles selected from the group consisting of glass, pumices, particles formed in situ from metal compounds that react with chloride, and mixtures thereof; wherein the nanoparticles increase the heat capacity of the coolant and enhance the heat transfer efficiency of the fluid composition.
