A new heat propagation velocity prevails over Brownian particle velocities in determining the thermal conductivities of nanofluids

<p>Abstract</p> <p>An alternative insight is presented concerning heat propagation velocity scales in predicting the effective thermal conductivities of nanofluids. The widely applied Brownian particle velocities in published literature are often found too slow to describe the rela...
