Multiwalled carbon nanotubes (MWCNTs) are being utilized to enhance the thermal conductivity of nanofluids, making them highly effective for applications in cooling systems, electronics, and more.


The high thermal conductivity of MWCNTs makes them ideal additives for nanofluids. When dispersed in a base fluid, MWCNTs create a percolating network that facilitates efficient heat transfer.

Thermal Conductivity of Nanofluids:

Multiwall carbon nanotubes and distilled water, laying the foundation for understanding their combined potential. The study navigates through the characteristics that make MWCNTs an attractive addition to distilled water, emphasizing the synergies between these materials for enhanced thermal conductivity.

How MWCNTs Enhance Thermal Conductivity:

Phonon transport: MWCNTs provide pathways for phonons, which are the primary carriers of heat in non-metallic solids.

Micro-convection: The presence of MWCNTs enhances the convection currents within the fluid.

Reduced thermal boundary resistance: The interface between the nanotubes and the fluid has lower resistance to heat flow.

 Preparation of MWCNT-Based Nanofluids:

Achieving a stable and uniform dispersion of MWCNTs in the base fluid is critical. Common methods include:

– Ultrasonication: Using ultrasonic waves to break up and disperse the nanotubes.

– Surfactants: Adding surfactants to reduce the surface tension and prevent agglomeration.

– Functionalization: Chemically modifying the surface of MWCNTs to improve their compatibility with the base fluid.

 Applications of MWCNT Nanofluids:

  •  Cooling Systems
  •  Renewable Energy
  •  Medical Applications
    From microelectronics to large-scale industrial processes, the versatility of this nanofluid in enhancing heat transfer is explored, pointing towards a future where advanced thermal management is more efficient and sustainable.
