Abstract
New heat transfer technologies are needed to reduce the net greenhouse gas emissions resulting from industrial applications. One such technology could be the use of ferronanofluids under the influence of magnetic forces to improve convective heat transfer. Our study presents an innovative approach for the production routing of the suspensions required for this purpose. The central idea is to start from a profile of requirements, which specifies the characteristics of the needed suspension with respect to the physical characteristics of convective heat transfer. The obtained ferronanofluid is experimentally characterized in detail with respect to its chemophysical and thermophysical properties. Its Newtonian behavior and the experimentally determined Prandtl number, which matches the values for water, make it a promising candidate for benchmark experiments on convective heat transfer.
期刊介绍:
International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
