Summary, etc. The formation of boundary layer takes place whenever an object is placed in the path of flowing<br/>fluid. This phenomenon of formation of hydrodynamic and thermal boundary layer is used in<br/>various engineering processes. This type of fluid flow can be expressed mathematically in<br/>terms of Navier-Stokes equations. The solution of the Navier-Stokes equations may help in<br/>creating better understanding of the said phenomenon and may also help in the creation of<br/>better and improved engineering processes. However, the exact solution of the Navier-Stokes<br/>equations for all fluid flow types do not exist yet, but the approximate solutions may be<br/>obtained using different numerical and analytical techniques.<br/>In this research, a system of partial differential equations (PDEs) of an unsteady film flow over<br/>a stretching surface with internal source of heat generation and thermal radiation is considered.<br/>An algebraic technique, Lie symmetry is used to obtain the Lie point symmetries of system of<br/>partial differential equations for constructing invariants and reductions. Multiple reductions are<br/>obtained to solve the fluid flow for different physical conditions. Then the deduced reductions<br/>are used to transform a system of partial differential equations into various systems of ordinary<br/>differential equations in order to apply homotopy analysis method, which solves the system of<br/>ordinary differential equations analytically.<br/>In this study, all systems of ordinary differential equations are solved analytically to investigate<br/>the impact of unsteadiness parameter, Prandtl number, internal heat generation parameter, and<br/>thermal radiation parameter on flow velocity, temperature and heat transfer rate. The study then<br/>presents the results of this analysis using both graphical and tabular formats. The study of thin<br/>film flows under different physical conditions can provide valuable insights into dynamics of<br/>fluid flows, and how they can be controlled and optimized for better performance. By<br/>understanding the impact of various parameters on the velocity and heat transfer rate, engineers<br/>can design and improve various engineering processes.
