Peristaltic flow analysis of thermal engineering nano model with effective thermal conductivity of different shape nanomaterials assessing variable fluid properties

Abstract

The current study is connected to a recent investigation regarding temperature-dependent viscous flow for various-shaped nanoparticles in a flexible tube. For velocity/pressure gradient/temperature, precise solutions have been determined. Cylindrical coordinates have been used to simulate the main flow problem, and the lubrication approximation method has been used to reduce the flow equations to ordinary differential equations (ODEs). For easier understanding, results are graphically discussed. Additionally, it can be seen that platelet-shaped particles have a smaller velocity field than brick- and cylinder-shaped particles. Further it is analyzed that if we add the specific brick-shaped nanoparticles to the fluid, the thermal conductivity of the fluid improves.
