The output power of a wind turbine can be significantly improved if we can harness the fluid dynamics surrounding a structure to increase the wind speed, specifically if we can catch and concentrate the wind energy locally. When compared to an open turbine with a rotor of an equivalent size, a shroud in a shrouded wind turbine serves to enhance the velocity of the air travelling through the rotor plane. This work aims on investigate the suitability of shrouded wind turbines for Kerala’s climatic conditions. For this, wind velocity data collected and analyzed. A basic model is created using ANSYS Workbench and CFD (Computer Fluid Dynamics) analysis carried out on the model created. Results shows that shrouded wind turbines provide an output flow velocity which is more than twice of input airflow velocity and turbulence intensity founded within limits thus helps to obtain high yields even for low wind speeds.

In the first instance, it makes sense to utilize this method to increase wind turbine output. If the velocity speed-up ratio is still positive at high upstream wind speeds, the duct’s influence will be decreasing at higher wind speeds. Wind turbines for low wind speed circumstances have recently been researched to efficiently convert wind kinetic energy into mechanical energy. There are a significant number of open spaces that could be used for wind energy. Potential areas for wind generation are abundant and accessible. The majority of Kerala state's energy needs are met by hydroelectric power, which in turn depends on water entering reservoirs but the floods of 2018 and 2019 that impacted Kerala reduces the extent to which we are dependent on reservoirs. In Kerala, there are very few fossil fuel resources, and the vast majority of its hydropower potential has already been used. The emissions from coal- or gas-based power projects in coastal Kerala may have a negative impact on the region's forests, vulnerable marine habitats, and human health. Given these numerous restrictions, Kerala's future energy security is at risk. Since most renewable energy technologies are known to have negligible environmental implications, Kerala's sustainable development and energy security would benefit from a planned transition to renewable energy. Issues with size, noise, flying animals, and other species are the primary topics of contention about wind mills installed. To solve these issues, the design of micro wind turbines has
