The pH value and viscosity of the nanofluids are also characterized. The experimental results show that the thermal conductivity increases with an increase of particle volume fraction. The particle size and shape also have effects on this enhancement of thermal conductivity. For TiO 2 particles of ...
The aim of this study is to investigate the effect of ultrasonication on the stability and thermal conductivity of TiO2 water nanofluids. A UV–Vis spectrophotometer was employed to determine the relative stability of nanofluids. Response surface methodology based on the Box–Behnken design was impleme...
The model based on the phonon Boltzmann transport equations with diffuse mismatch interface conditions has been used to calculate the lattice thermal conductivity of SrTiO3/TiO2 nanostructures. Result shows that in the superlattice nanowire structure the interface scattering cause the reduction in phonon ...
