Metal based nanofluid thermal conductivity through MD

Dear All,

Many researchers till date have done the MD simulation on metal based nanofluid to determine its transport properties. However through MD, electronic contribution of metal to the enhanced thermal conductivity is nullified as MD can only capture the lattice contribution towards the enhancement. But in metals main carriers are electrons not phonons. So while calculating the thermal conductivity, phonon contribution is less than electron. So according to me while simulating the real system,we should consider the electronic contribution as in real life the picture is different.

  1. Are the results published in very good journals with metal nanofluid on enhanced thermal conductivity reliable?

  2. Can we just simply ignore the electronic effect and just see the phonon contribution?

  3. How accurate our system properties are when we ignored electronic contribution in calculating thermal properties of metal based nanofluid?

It will be of great help for my understanding. Thank you in advance!

Dear All,

Many researchers till date have done the MD simulation on metal based
nanofluid to determine its transport properties. However through MD,
electronic contribution of metal to the enhanced thermal conductivity is
nullified as MD can only capture the lattice contribution towards the
enhancement. But in metals main carriers are electrons not phonons. So while
calculating the thermal conductivity, phonon contribution is less than
electron. So according to me while simulating the real system,we should
consider the electronic contribution as in real life the picture is
different.

1) Are the results published in very good journals with metal nanofluid on
enhanced thermal conductivity reliable?

as much (or as little) as any published research. reliability of
research is not evaluated based on surveys or opinion, but by
confirming or refuting the claims of a publication by careful and
thorough research.

2) Can we just simply ignore the electronic effect and just see the phonon
contribution?

it depends.

3) How accurate our system properties are when we ignored electronic
contribution in calculating thermal properties of metal based nanofluid?

only a careful comparison of a well crafted simulation with a
corresponding careful and accurate experiment for the system in
question can tell.
