摘要：
A new model which includes liquid molecule nanolayer, aggregation and nanoconvection is developed to discuss the enhanced thermal conductivity of nanofluids. Dimensionless numbers (particle size and thermal conductivity) are firstly defined, and it is confirmed that the particle size including powder and aggregate sizes is one of the key parameters to affect the thermal conductivity. It is found that the maximum enhancement of thermal conductivity is to be 64.4 %.
