Thermal properties of aqueous silver nanoparticle dispersion

Distilled water has wide range of heat transfer applications. However, it begins to decompose less than 80 degrees C in the thermal systems. To enhance the ability to resist the thermal decomposition and evaporation silver nanomaterials are homogeneously dispersed into the Distilled water. The thermal properties of the base fluid (Distilled water) and silver nanofluids estimated through the thermogravimetric analysis (TGA), differential thermal analysis (DTA) and differential thermogravimetry (DTG). Results show that the evaporation and decomposition rate of water molecules reduces to 93%, 29.9%, 41.3% and 125.9% for the temperature ranges of room temperature-40 degrees C, 40 degrees C-60 degrees C, 60 degrees C-80 degrees C and 80 degrees C-100 degrees C, respectively due to the dispersion of silver nanoparticles.

Automated summary

It was found that uniformly dispersing silver nanoparticles in distilled water can significantly reduce the evaporation and decomposition rate of water molecules within certain temperature ranges.
