Comparison of the Hydrodynamics for Pressure – Driven and Acceleration – Driven Poiseuille flow

A study on the comparison of the pressure-driven Poiseuille flow and acceleration-driven Poiseuille flow was made by analyzing the resulting models of the flow configuration. It is shown that at the hydrodynamic level, there exist a difference in magnitude of the two flows but at the microscopic level the body force and the pressure gradient which are the driving forces are different due to spatial variations in the both flows.
