Hydrodynamic and thermal flow in nanochannel to study effects of roughness by estimation the atoms positions via MD method

Abstract

Purpose This paper aims to investigate atoms type and channel roughness effects on fluid behavior in nanochannel. Design/methodology/approach The results of mechanical properties of these structures are reported in this work by using molecular dynamics method. Findings The results show that nanochannel roughness is a limiting factor in flowing fluid in nanochannel. Moreover, fluids with less atomic weight have more free movement in ideal and non-ideal nanochannels. Originality/value For the study of mechanical properties of fluid/nanochannel system, the authors calculated parameters such as potential energy, density, temperature and velocity profiles of simulated fluids.

Develop artificial neural network numerical modeling to study fluid flow and heat transfer of dispersed nanoparticles through base liquid

“…The SiO 2 and the CNT-SiO 2 deviations decreased almost 0.00705 and 0.004425%, respectively, individually. It is well-known that heat transfer enhanced after: increasing in the “Vol.%” (Das et al , 2003); “T” increment (Sarkar and Selvam, 2007); adding CNT (Jha and Ramaprabhu, 2009), to the Silica/Water mono nanofluid; however, the present work method had not been used before (Salimpour et al , 2020; Peng et al , 2019; Wu et al , 2019; Rajabzadeh et al , 2019; He et al , 2019; Bagherzadeh et al , 2019).…”
