The present study numerically investigates the effects of the variations of thermal conductivity and viscosity with temperature on velocity and temperature fields. The simulation is performed in a two-dimensional steady channel flow. The velocity profile is first validated against its analytical solution for the case of constant properties. A good agreement between numerical and analytical solutions is observed. From a physical point of view, it is revealed that by increasing the temperature in liquids, the fluid elements near the high-temperature wall are moving faster compared to those adjacent to the low-temperature one.
