thermal conductivity

hello dear

i’m simulating the nanofluid water and cu. to compute the thermal conductivity.

i have attached the diagrams.refers to the inkropera book thermal conductivity (T.C) of water increases with increasing the temperature and decrease in 530 kelvin.

but in the diagrams there are some maximum and minimum that i can’t understand them.but refer to an article there are some reasons in below:

1-brownian motion

2-clustering nanofluids

3-nature of heat transfer in nano particles and heat transfer of fonouns

4-nano layers made between nanofluids and base fluid

are the diagrams reasonable?does any body know any reasons?

i appreciate any helps

sincercely

notebook 1:prediction of T.C of water at different temratures(no nano particle)

notebook 8:it is related to voloume concentration

notebook 4:prediction of T.C of nano fluids at different temratures with 8.5% nano particle
notebook 2:prediction of T.C of nano fluids at different temratures with 5% nanoparticles

You’re not asking a LAMMPS Q. Asking why did my LAMMPS

simulation not reproduce some paper or book is not generally

easy to answer.
