    Pakistan is one of the countries in the world that is still suffering from an electricity shortage crisis. Even some areas of the country are untouched by the basic facility of electricity from head to toe. Generating electricity using non-renewable sources is not only further damaging society but also increasing the cost of the facility being provided. Hence, producing power from renewable sources of energy is a major challenge faced by the world. Being blessed with numerous bodies of flowing water having low heads, the Archimedes screw turbine is chosen for producing energy using the low-head sites in villages in Pakistan. Utilizing SOLIDWORKS, the turbine is modeled. SolidWorks software was used to aid in the designing process of the prototype, allowing the parameters to be varied accordingly. This design was validated numerically on CFD software, where different results were depicted to understand and visualize the outcomes. The design of the turbine is optimized using a variety of criteria. CFD simulation is used to estimate the torque and optimize the design. The calculations start with initialization and use the volume flow rate as a boundary condition, allowing the pressure and velocity profiles to be viewed. Torque is calculated using various parameters employed in the optimization of the turbine, i.e., turbine inclination angle and the number of blades. For a turbine with a 25° inclination, it was discovered that three blades provide the best torque. The turbine's spin started to slow down after the number of blades exceeded three due to increased resistance that obstructed the water's passage, causing the turbine's speed to slightly decrease because of greater contact with the water. It has been discovered that the turbine blade's maximum torque or power may be produced based on the turbine's inclination angle, water flow rate, and trough diameter. The turbine produces a torque of 0.1586 Nm. Because the average water velocity at the entrance is utilized, this number is minimal when used as the data to calculate the volume flow rate. Domestically accessible tube well water supplies may be used to generate energy. A prototype is then created so that the findings may be compared. A system is developed by printing a turbine blade on a 3D printer and assembling it with other parts.
