I have a simulation that by adding nanoparticles to paraffin the rate of entrainment first increases then decreases and then increases over time. Is this a logical process?
the melting process of Cu/water nanofluids PCMs by using enthalpy-based LBM. The numerical results had a good agreement with the previous numerical results in describing the convection-dominated melting.

Paraffin melting is a first-order phase transition. There are three different processes for adding nanoparticles. 1. The specific heat capacity of nanoparticles is greater than paraffin. You heat up. Heat first take the nanoparticles, then transfer it to paraffin. 2. The specific heat of the nanoparticles is the same with paraffin. Nanoparticles will melt earlier than paraffin as a result of the size effect. Competition is possible depending on the composition 3. The specific heat capacity of the nanoparticles is less than paraffin. At first, paraffin will melt, and then nanoparticles.
