Carbon-based nanomaterials are showing promising potential in a variety of applications. Owing to their distinctive structure, multiwalled carbon nanotubes (MWCNTs) posses unique thermal, mechanical, and optical properties. These properties allowed MWCNTs to surpass other nanomaterials when it comes to nanofluids’ applications. They are proven to have a significant role in the overall fluid thermophysical characteristics. This role can either be in compliance with the application requirements or not. Besides, this role’s scale depends on the magnitude of the interaction between the MWCNTs and the base fluid molecules. In this chapter, the underlying mechanisms that govern these interactions are discussed, focusing on nanofluid stability, thermal conductivity, heat capacity, wettability, and rheological properties. Besides, two main applications of MWCNT-based nanofluids in metal cutting and solar energy are provided. This work aims to provide an in-depth and holistic understanding of MWCNT-based nanofluid properties and how these properties affect the nanofluid performance in different applications.
