The potential of nano-lubricants to improve heat transfer and flow characteristics in a variety of engineering applications has motivated a significant amount of interest in the study of their thermophysical properties in recent years. This paper examined the influence of thermophysical properties, including thermal conductivity, viscosity, density, and specific heat capacity, on the heat and flow behavior of aluminum oxide (Al₂O₃)-based nanolubricants that are flowing through a cylindrical channel. The governing equations for momentum and energy were converted to non-dimensional form and solved using a finite difference scheme that was implemented in C++. The analysis examined the impact of thermal conductivity (0.3<κ<1.5), viscosity (0.001<μ<0.3), density (998< ρ <3592), heat capacity (1100 < Cp < 4200), and the Eckert number (1.0
