Proc. ASME. FEDSM2022, Volume 2: Multiphase Flow (MFTC); Computational Fluid Dynamics (CFDTC); Micro and Nano Fluid Dynamics (MNFDTC), V002T06A001, August 3–5, 2022
Paper No: FEDSM2022-86966
... Abstract This present work studies the effect of single nanoparticle diameter on a nanochannel fluid flow and convective heat transfer using the molecular dynamics simulation code LAMMPS. The channel dimensions are 95 Å in length, 40 Å in depth, and 60 Å in height. Channel wall temperatures...

... of the Prandtl number on convective heat transfer from a blunt disk. A primary and a secondary effect were distinguished based on the rigorous analytical treatment. The boundary layer theory offered a rather efficient calculation method, and its results were in an excellent agreement with available literature...

... with the increase of porosity due to the same reason. It is noted that temperatures of the solid and gas phases of the aluminum foam decrease as Reynolds number increases, caused by the increased convective heat-transfer rate at higher Reynolds number. The deduced temperature difference between solid and gas phases...

... was investigated, for different flow regimes, and correlations were proposed for the flow friction and heat transfer characteristics. Fully turbulent convective heat transfer was achieved in mini channels at lower Reynolds numbers compared to conventional sized channels. Critical Reynolds number for flow...
