Abstract
This study is motivated by the controversies on nanofluids reflected in recent literature. Eight hypotheses considering the subject’s measurement of thermophysical properties, evaluation of heat transfer experiments and numerical modeling are discussed. Two of them are illustrated employing the most recent experimental results by the authors. Keywords: nanofluids, experimental difficulties, further work. 1 Introduction Confronted with limited energy and material recourses and undesirable manmade climate changes science is searching for new and innovative strategies to save, transfer and store thermal energy. One of the currently most intensively discussed options are the so-called nanofluids. The number of publications with respect to nanofluids is exponentially growing since the beginning of our millennium (Fig. 1). However, many publications indicate controversial results.
