Project Summary

My project is to design and analyze Vortex Bladeless wind turbine. The project is divided into two part; design and analysis of turbine in computational software, and fabrication of turbine. 

The first approach to the project is to design a bladeless wind turbine in CAD. As bladeless turbine has a simple geometry it can be modeled on space claim or design modular of ANSYS or can simply be made using CATIA. The basic design of a bladeless turbine is a simple cylinder. For better understanding of bladeless turbine more models will be designed with different parameters of changing length, diameter, and taper ratio. The other major thing that is to be selected after the design is the material used for the turbine. The material can be used from the literature. In literature,
it can be found what type of materials others have used mostly, which is carbon fiber, but carbon fibers are relatively costly so, other materials having less efficiency, but a better cost can also be selected, such as glass fiber material. Or material of our own choice can be used after analyzing its properties.

After the turbine is being modeled, it is to be analyzed. The software that will be used is ANSYS (fluent). The different models of the bladeless turbine will be analyzed under same conditions so it can be compared with each other. The analysis can also be further divided into two parts, 2D and 3D analysis. Both analyses will give different types of results and data. The foremost result in case of bladeless turbine is the frequency of the turbine with which it will vibrate under certain conditions. As it is well known ANSYS is an approximation method to solve problems, so none of the answer is entirely correct, or entirely wrong. So, the results we will be getting from ANSYS must be validated with some theoretical results already existing in the literature, or it can also be validated with experimental data.

Once we have done the analysis, our dimensions and material of the turbine is selected. The fabricated scale down model of turbine is then to be placed in wind tunnel and analyzed to get experimental values. The major problems with fabricating a turbine are, that the height of a bladeless turbine is usually around 1 meter and above, such height cannot be used for in the wind tunnel we have. So, it must be scaled down. The problem with scaling down is that with the same material of 1 meter length it is flexible, but as its height decreases it will get more rigid and same results cannot be produced in wind tunnel. So, to make a scale down model the material we will be using won’t be the same material, but a material must be found having comparable flexibility at short length, for this, equations in literature can be found and a suitable material will then be selected, and turbine will
be fabricated and analyzed in wind tunnel.

Project Objectives

The objectives of the project are: 

• Study of aerodynamics of the wind turbine
• Designing a bladeless wind turbine in CAD model
• Computational Fluid Dynamics analysis on CAD model, at different conditions and with varying dimensions
• Optimization of different parameters of wind turbine such as, Lenght, taper ratio, and diameter
• Scale down and fabricating the optimized model of the wind turbine 
• Wind tunnel testing of scale down model of bladeless wind turbine 

Project Implementation Method

The idea of bladeless wind turbine is reletively new, not much research has been done on this concept. Bladeless wind turbine after much research can be implemented or commercialized. Bladeless wind turbine can be implemented at areas where wind flow is considerable such as, costal areas and hilly areas.

Benefits of the Project

Pakistan is a third world country. Pakistan has always faced crisis of energy. Bladeless wind turbine is an efficient source of power. Unlike convenetional wind turbines, bladeless wind turbine have number of advantages over other turbines. It is less complex, low manufacturing cost, low maintenance cost as it has less moving part, no gears or lubrication required, possess no threat to wild life, hence producing low cost energy. According to pakistan topology, there are many areas where average wind speed is considerable and bladeless wind turbine can be implemented at such areas. 

Technical Details of Final Deliverable

Technical details of final delivereables are:

• Dimensions of the wind turbine must be optimized using the CFD software ANSYS
• Force exerted on the turbine by the wind must be determined
• Frequency with which the turbine will vibtrate must be determined
• To model the wind turbine in ANSYS material must be chosed with high flexibilty and flexural strength
• Outer mast should be light weight and must be made of light weight material such as composites
• For fabrication of scale down model material should be chosed which mimic the actual model
• Wind tunnel testing must be done to verify the results from ANSYS
