The main goal of this keynote is to provide researchers with a guideline for avoiding common mistakes in convective nanofluid research. Nanofluid is an engineered colloidal suspension of nanoparticles in a conventional heat transfer fluid called base fluid. Research in convective nanofluids is one of the most attractive research areas in the field of heat transfer. Although nanofluids' thermal conductivity and viscosity have received the most attention, many researchers have recently attempted to study different heat transfer characteristics of nanofluids experimentally and numerically. Therefore, nanofluids are in the spotlight for various applications. However, the field's progress is hampered by (i) a lack of consensus amongst researchers' findings; (ii) poor characterization of dispersion and stability; (iii) lack of hybrid theoretical models for properties; (iv) a lack of an accurate nano-scale heat transfer formulation; (v) errors in scholarly journals due to a lack of knowledge and/or citing incorrect published information. This keynote provides a straightforward way to evaluate experimental and numerical publications on convective nanofluids research until such time that researchers no longer make these common mistakes. This also helps the reviewers of journals provide consistent comments for improving the manuscripts and finally make more accurate decisions while evaluating manuscripts.
