Outcomes
Objectives
- Development of quantum-dot containing fluid with increased thermal conductivity at close to ambient temperatures
- These fluids were added to enhance heat transfer capabilities of water-based fluids used in industrial cooling systems
Outcomes
- Hydrothermal synthesis results in samples with slightly enhanced thermophysical properties at the target temperature range
- Quantum dot formation in fluids was confirmed from TEM images (2-5 nm)
- Minor improvement of ∼6.2% was observed for the dispersion thermal conductivity for a specific addition level while the specific heat capacity showed a modest change
